Seems generally reasonable. Maybe rephrase 3 as "We consider only
an OS release's default LLVM version"? Or a bit more forgivingly,
"... only LLVM versions available from the OS vendor"? Also,
what's an OS vendor? You rejected macOS which is fine, but
I think the packages available from MacPorts or Homebrew should
be considered.
You could imagine somebody trying to game the system by standing up a
buildfarm animal running some really arbitrary combination of versions
--- but what would be the point? I think we can deal with that
when/if it happens. But "macOS running an LLVM version available
from MacPorts" doesn't seem arbitrary.
