Discourse uses the email address as the identifier. If you do something more to check their identity, then you know it’s that person. I’m not clear how it I were to change my name it would make me a different person. What damage is done if Jay Pfaffman changes their Gmail name to Jay A. Pfaffman? Or anything else?

Discourse by default will ignore what name they set on Gmail anyway.

You can disallow changing usernames.
