Sidenote: codecov: I wanna tag this (if for nothing else than my own personal reference) as one of the kind of things that made me ditch the codecov service in some other projects. This report it made is... objectively and trivially nuts.

Claims coverage has gone down. Huge red squares. Looks like fire and klaxons. And it reports this as a "fail" of the check.

On a diff that's entirely renames, and has no flow changes whatsoever, and is line-for-line 1:1 the same length before and after in all code files.

Uffdah. No, codecov. That is not helpful.
