What I typically do is to disable optimization in a release build.
It then essentially becomes a debug build, except that _DEBUG is
not defined, so that it doesn't incorporate the debug CRT. This,
in turn, means that you can mix such a "debug" build readily
with non-debug binaries.

Sure - all understood, and all fine. It's certainly good to build
consensus first, but in cases of "should we support that borderline
case of build setup as long as I'm willing to maintain it", the
answer should always be "yes" (*), irrespective of the merits of the
specific proposal. Heck, we would even accept patches to support
HP-UX better :-)


(*) assuming it doesn't break anything
P.S. I think there have been cases where I haven't been that
supportive wrt. build issues. However, in this case I really
feel "go ahead".
