Changes between Version 1 and Version 2 of Ticket #57967, comment 18

v1	v2
3	3	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.

5		There seem to be few edge cases. For example when a user changes their email address a~~fter they used an email as a username or their~~ new email matches another user's 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".
