Ah, I wasn't trying to say those were the only two options, or that either was what you were suggesting. I also typically prefer other things.

I just find that "always squash the entire branch" is a common reaction to "history is messy" and I wanted to surface that (per my understanding) it doesn't actually improve the situation (vis-a-vis bisect in particular, assuming you're passing the correct arguments for your situation) over merging (no-ff, I neglected to specify...) branches where some of the commits do not build.
