Pretty much agreed with the other changes, thanks for the review!

But this diff-stat change, indeed, it is unfortunate that we end up
with more code here than before. We'll try to reduce it instead
somehow, however in some cases during this spring-cleaning, since
the goal is to move code from one file to another, it *may* require
more code. So it won't always be negative. But we'll try!
