Relevant to this: I wonder what we think the supported macOS versions
are, anyway.  AFAICS, the buildfarm only covers current (Sonoma)
and current-1 (Ventura) major versions, and only the latest minor
versions in those OS branches.

I share Peter's unwillingness to assume that Apple hasn't randomly
fixed or broken stuff across toolchain versions.  Their track record
fully justifies that lack of trust.
