I don't really understand why you insist on using such inflammatory 
language; all this stuff is ABI constants, and the only reason glibc 
doesn't use them is that glibc prefers to use enums over #defines.

Right now, glibc is special-cased.  glibc also tends to be very 
deliberate about its kernel header inclusions.  It wants a subset of the 
available defines, so it can include a subset header.

The reverse is definitely possible too -- all other users (kernel, 
newlib, dietlibc, uclibc, and klibc) can change and leave the current 
state for glibc.

We can special-case the kernel in the above case, but that would involve 
some additional ugliness.
