But aren't we talking about squashing those commits? You're not going to lose anything by skipping commits between PRs instead of squashing everything between PRs into one commit, you can only narrow it down more.

Yes, which you can tell to skip anything that doesn't compile/pass tests. Return 125 from your script and it'll be skipped.

But you can just do a loop of "make || git skip" and skip everything that doesn't commit, surely. Or if you're using a script, just return 125 for things you want to skip.
