And that's absolutely sane. But I think it's useful to keep tabs on what
we do have — where we have patches which are sane for upstream they
should be pushed that way as rapidly as possible, and where we have
workarounds for LLVM they should clearly identify the PR# that they
address. Looking through the patches we have at the moment, it's
sometimes hard to tell what's being fixed, and why.

For example,
gives me *no* context about what the problem is or where to find the
existing discussion about it.

Yeah, absolutely. If you want to let me have simple patches with a clear
commit comment I can certainly shepherd those upstream.
