Thanks for the comments @arsenm @yxsamliu @b-sumner.

By approaching a similar solution, do you mean MMRAs (https://github.com/llvm/llvm-project/pull/78569) ?

If so, should I rebase/adapt my patch to the MMRA PR? Or will this PR be redundant and needs closing?

@yxsamliu These concise names look good to me.
