As someone who has often had to dig into the history to figure out what happened, I always want to see at least this. And I wouldn't be opposed to seeing it broken down even more as it was worked on. Not one big squash merge that hides what really happened.

I'll also add one more to your list: Any improvements that came out of the review but stayed in that merge should each be individual commits. I've seen hard-to-trigger bugs get introduced from what should have been just a style improvement.
