I think you're conflating two independent things.

If you override the dpkg maintainer to remove that warning that occurs on 
derivatives, then anyone could NMU dpkg and the maintainer wouldn't introduce it 
back, effectively removing the warning from "dpkg upstream".

OTOH if the dpkg maintainer switches to non-native packages, anyone could NMU it 
adding the change as a patch, however the maintainer will just NACK the NMU 
before or after it happens.

So I don't see a problem with dpkg being native, just like e.g. apt is, and that 
won't magically solve the issue at hand.

Cheers,
Emilio
