@ShadowWizard Hmm, that's an idea. There's a few low rep users retagging on SO and
it was discussed there. I did some SEDE queries to try to think of ways to slow them down. If that feature request was implemented, then it would be trivial to extend it to say: a user can only retag a question if they have at least a positive score in their tag list. I have 55 tags in my SO tag list, so I should only be allowed to suggest edits on those tags.
