SGTM - I think that should come in a separate patch. I have a branch with all my changes on it (not stable, I rebase semi-regularly) [here](https://github.com/SLTozer/llvm-project/tree/llvm-project-coverage-tracker), where the patches can be divided into 3 categories: bug fixes, the coverage tracking feature, and a variety of random tweaks and features I've added to display info and help myself triage bugs. I haven't yet put any work into getting the last category merge-ready, but I think that would be the appropriate place for such documentation to go.
