Anything left to merge this ?

Looks plausible to me, but I am not familiar with the code.

It seems some more linting was turned on, which prompted some other, mostly cosmetic, changes. I always look for consistency between the description and the diffs, since it can reveal changes included by mistake.

I'll narrow this to fit title and provide another PR for the formarring
