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. regards, tom lane
