Revert it is, I guess.
I'm not trying to be hostile or chase you off (to the contrary, I
would greatly appreciate help rototilling make, as it needs a lot of
work) but we can't go arbitrarily breaking features that it's had

No. Breaking things that were never well defined or that nobody in
their right mind would have done on purpose is different from breaking
intentional features that people rely on. We've done lots of the
former; the problem is that we discovered after the fact that this set
of changes did the latter.
Even intentional features can be deprecated (and have been in the
past, and will be in the future(*)), but it takes time and planning.
