Personally I think the commit messages have somewhat lost its value to describe what has been changed between commits as the commit message includes "fixup! fixup! fixup! ... " but not what the change is about.  I could click "Commits" and then click the individual commit - and I need to do it 10 times with relatively little information for each click.
I think GitHub's comment preserving has been greatly improved, and nowadays we will just see "outdated" but otherwise no negative effect.

At this point, I think a rebase isn't that bad, especially for new reviewers who want to look at this change. That said, you have been reviewing this patch so far (thanks!) and I am happy that your opinion takes precedence.
