Comment (by jdgrimes):

 This would cause issues for any plugin that is storing usernames as a way
 to identify users rather than IDs. Yes, IDs should generally be used, but
 the fact that usernames cannot change may mean that some plugins out there
 are doing it. I can't say I know of any off of the top of my head, though.
 Unless you count BuddyPress `@mentions`, though I don't know for sure how
 those work. Anyway, it would be possible for plugins to match a username
 up with the correct user by checking the usermeta, I guess, but I thought
 that this potential back-compat issue was worth mentioning.
