Fine, I'll do it, but I don't think we really gain anything other than more make work right now given that the numbers will not be and aren't expected to be the same on a refactor (I wouldn't even bet on preserved ranking in this case). We have release notes to document changes. We have long github discusions on almost every merge. I'm not sure what a regression test for HuberScale would do when you can also just look at before/after your changes.
