in my opinion (the one where i don't care what anyone else thinks kind) you shouldn't be using tags on your working branches and your mainline/release branches should only be the ones where tags exists.
This then means that the only place you should be rebasing is your working/feature/pr branches and that when you merge your working/feature/pr branch, it should get squashed into the target branch... No one cares about your fifty gazillion 'wip' commits.
