Well, my limited experience with feature removal says that people only
say something when the feature is *actually* long gone, several releases
have passed by and the removal has finally percolated downstream.

I guess you could Cc arch maintainers with the a.out-core.h removal
patch to see if anyone screams.

Sure. And it can be reverted very easily if someone runs out of the
woods later and handwaving about an important a.out use case on x86.
Although x86 should be in ELF-land for a quarter of a decade now.

Thx.
