Yes. I'm really not sure what glibc's current policies are meant to
accomplish. They don't serve any useful purpose. There seems to be
this weird subtext that glibc has leverage to change OS design, and it
really doesn't. It's a misplaced idealism and ends up just hurting
everyone.

That's a separate point. Yes, gettid should have a wrapper, but *also*
we should have an FD-based interface to processes, because outside
specialized contexts (e.g., parent-child waiting), the traditional
Unix process API really is impossible to use safely. But that's a
separate ongoing discussion.
