LLVM has been out-of-date for almost six months now, which means the release cycle has come around again and LLVM 17 is on its third rc approaching release. If the wait had lasted a couple more weeks LLVM 16 could have been marked out of date while still in staging.

The last time a toolchain component got this out of date there was an acknowledgement about what had happened and there was improvement going forward. This isn't a complaint about TUs being "lazy volunteers" or some shit (if Arch disappeared tomorrow I wouldn't have any right to complain), just an ask for "what happened here?"

LLVM 16 isn't a trivial release. It brings clang-scan-deps which is necessary for C 20 named module support.
