Comment (by johnrom):

 Since it is only used during user creation, I don't think a second filter
 will hurt, performance-wise. Deprecation would be fine. For forward-
 compatibility, another plugin could set the username to false and break
 mission-critical functionality. If I'm not mistaken, these are the only
 places the username is exposed on a filter between user signup and the
 redirection when creating a user in multisite.
