 Replying to [comment:16 spacedmonkey]:

 Thinking no. This is a ticket to fix/revert the regression for 6.2. After
 that is done the original #57394 can be milestoned for 6.3, or a new
 ticket can be opened to implement the checks needed when email is used as
 username.

 There seem to be few edge cases. For example when a user changes their
 email address after they used an email as a username. Then there are
 additional complications as there weren't any similar checks in WP until
 now, so this has to be backwards compatible and not block editing of
 existing users even when their name/email is "incorrect".
