OK, I think I see where you are coming from.  My interpretation of that
discussion is a bit different.

To my mind, that discussion was mainly about what people use in their
day-to-day hacking on Emacs, because that's where the disruption happens
when the build is broken even if it's only broken briefly.

I think that's mostly GCC (and clang to some extent) on GNU/Linux,
macOS, MS-Windows and perhaps even a few of the *BSDs.  AFAIK, the
commit didn't affect any of those, but only more unusual ones that none
of our regulars use.
