It looks like we have an inconsistent approach to adopting LLVM/clang minor versions. We should likely revisit that.

Ideally, we'd move forward with minor versions to ensure we pick up any security of performance updates. We also would need a way to validate those updates with runtime before publishing. We likely do that with some fancy (with some definition of that term) manifest.json edits to produce a new tag name for a temporary period.
