Well, now I believe the #2 purpose is the design intention, based on this
section in Auth.register():
table_user = self.table_user()
if self.settings.login_userfield:
username = self.settings.login_userfield
elif 'username' in table_user.fields:
username = 'username'
else:
username = 'email'
In this case, I believe #1 is a bug and need to be fixed.
