Why do rear pannier racks have a raised “nose�

I am tempted to saw off the raised "nose" on my unbranded 2nd hand pannier rack because it's forcing me to lift the child seat substantially, which obviously has implications on stability. But I feel there must be a reason so many racks have this raised nose thing. I had a look at this article, and it hints towards stability/structural integrity, but I cannot see how the nose would help (I'm in engineering but not a structural engineer). My only other thought is that it's an added measure to stop items sliding forward, but it feels like there's something else I'm missing. Does anybody know what the nose is for? Has anyone cut it off and how did that go?
NB I purposely avoided using "the F word" ("opposite to rear") to describe where on the rack the nose is - this is meant to avoid this cropping up in searches related to f***t panniers.

It is to stop the load sliding forward under braking, or even from the pressure of the clamp (?) part of the rack.
It also provides a wider part into which the rack can push the item firmly. If it were left to the seat post, that's one round post and not a wider ledge for support
Also, if you're a bungee user then it provides a higher point with corners to hook onto, so the hooks are less likely to slide. Suspect this is more of a side benefit.
Personally I really dislike when things touch my legs while riding, like the end of the brake cable or a light fitting, or any part of the load.
On the downsides, the lippy bit makes larger items a bit harder to put flat on the rack.
It also adds a tiny bit of weight and aero drag.
Separately, having the load a bit further back increases weight on the rear wheel which moves the weight distribution aft, and this contributes to making the front tyre more lifty on a climb.
If you cut off the lip, you'd probably have to add some flatter bracing.
To get the kids seat to work better, consider removing the rack completely for as long as you need the seat. If you need to move something, then put the load into the kid's seat. This will also increase the overall riding stability because the child will be a bit lower.

A good explanation (+1) but I have to disagree with the last paragraph - quite often the reason you need to transport stuff at all is because the seat is occupied, and a small-ish pannier will often fit at the same time as a seatpost-mounted child seat. I ran like that for nearly 5 years and would like to find a solution to mount a rear pannier with my new child seat

I think you are correct that it’s only to prevent items from sliding forward and falling off or colliding with your legs/hips. This is only really important if you use the spring loaded clamp. A lot of racks (I think all of them without the spring loaded clamp) don’t have this “noseâ€Â.
Since there is still another horizontal bar right below it I don’t think removing it will affect stability. Just make sure to cut it cleanly, remove any burrs, plug the hole and apply some paint to prevent rust.

+1 but I do have racks without a spring and with a nose or prongs to serve the same job (Tubus, Topeak). You can after all strap items to the rack with the spring

Pesonally I'd replace the rack. When using a Hamax Siesta child seat I fitted a Tortec Velocity Hybrid rack.
In your specific case though, given that there's a cross-brace at the bottom of the part you want to cut off, you'd be fine to cut it. If you later want to put items on top of the rack, tie a bungee cord to the front and hook it at the back.
If you're really worried about the high centre of mass, doing away with the rack would help -- but I assume you need it. It may be possible to make the rack sit lower if you remove the mudguard and build a new mudguard around the rack. Here are some hints. The rack itself may have an extra set of holes or may need modifying.
A tip for you when you lower the seat: it will flex more than you think, and the seat banging into the rack is annoying for you and your passenger. Keep a bit of clearance and/or strap some foam padding to the rack.

Pesonally I'd replace the rack. When using a Hamax Siesta child seat I fitted a Tortec Velocity Hybrid rack.
In your specific case though, given that there's a cross-brace at the bottom of the part you want to cut off, you'd be fine to cut it. If you later want to put items on top of the rack, tie a bungee cord to the front and hook it at the back.
If you're really worried about the high centre of mass, doing away with the rack would help -- but I assume you need it. It may be possible to make the rack sit lower if you remove the mudguard and build a new mudguard around the rack. Here are some hints. The rack itself may have an extra set of holes or may need modifying.
A tip for you when you lower the seat: it will flex more than you think, and the seat banging into the rack is annoying for you and your passenger. Keep a bit of clearance and/or strap some foam padding to the rack.
