No. To the extent that I can however I do restrict myself to only non-broken commits. > If there were even 2 non-broken commits in the PR, then bisecting with the original history lands you on a diff half the size that bisecting with squashed history would, which is a significant win It is not a significant win when the bisecting session keeps landing me in your broken commits that I have to waste time evaluating and skipping.

If you want to ignore the individual messages and just look at the PR-time message that's easy too. Neither of these is true. git bisect (run) lands me on a commit, it’s broken, now I need to look whether the commit is broken in a way that is relevant to what I’m seeking. > Better to have the extra details and not need them than need them and not have them.

Skipping a commit that doesn't build is trivial (especially if you're automating your bisects).

If you feel the need to rebase to squash one-liner fixups into the commits they fix then that's a more subtle tradeoff and there are reasonable arguments. But squashing your whole PR for the sake of that is massive overkill, and the costs outweigh the benefits.
