For updating the PR branch:

The whole branch gets squashed when merged anyway. A merge reduces the chance for pushing already existing commits that changed during rebase, causing other people to be tagged as well. Having additional commits for things done after the review has started instead of fixing up the original commit and force-pushing has the benefit of showing the incremental progress that GitHub does not correctly show when force-pushing.
