At least when I introduced X86_GENERIC it was just an optimization,
not a requirement.

That is the kernel pretty much always did "just work"
(with only a very few exceptions like PAE vs non PAE) on all
CPUs. The CPU configs also just specified optimizations, not correctness.
The code for all CPUs used to be always there.
X86_GENERIC was mostly just to do things like always use
the largest cache alignment.

I think someone changed that recently, but imho that wasn't
an improvement. As you can see it just causes endless support
problems.

Well it's more like that you guys changed the semantics
without warnings the distributions. I'm not sure you can blame
Debian for that.
