However, the precommit CI behavior confused multiple Clang contributors (I also thought the bot was misconfigured because Clang tests are never run against old Clang versions), the output did not clearly identify what was wrong or how to address it, and the difficulties with testing this locally are all things the libc++ maintainers should also keep in mind.

That's a great question to be asking, so thank you! I'm not on Discord (still on IRC though), but I'm happy to chat about it via whatever means works for us.

At a high-level, I think it boils down to familiarity. If we can get the libc++ CI to run as part of precommit CI (assuming precommit CI can be made to run with reliable results, which is a bit of a question mark), then I think that will help get all clang contributors more familiar with the libc++ testing behavior over time, because we'll be far more used to seeing it when we cause a failure. It would have also helped to catch the cause for the initial revert where everyone thought the patch was ready to land. Another thing that would help would be to get the libc++ test bots into the LLVM lab (https://lab.llvm.org/buildbot/#/builders) and ensure that they're sending failure emails to everyone on the blame list including people who land a patch on behalf of others. It looks like we have one builder for libc++, but it doesn't appear to be working recently: https://lab.llvm.org/buildbot/#/builders/156.
