> Some examples: - Sending a large PR that changes many files at once because their changes kept growing in scope as they were trying to figure out how to do something.

I'm the most senior developer in my team. Normally I block the PR with a change request and say exactly what I want, i.e "Please commit X and Y, in a new PR" and I give exactly the commands that this developer must run. Then, after this small PR is merged, I ask the developer to rebase the huge PR with the master, and do that until the initial PR get as small as possible. If you are not the manager or not team lead, the easiest way is to lead by example, mostly by doing together. Sometimes it can be frustrating, but I'm sure I bring those stuff up when I'm negotiating my salary raises...
