Ugh, this is just a nasty change. usernames will rarely, if ever,
change and I don't like the idea that users can change their username.
A principal name of "bill" is much more coherent than
"2341235234234-234123-234123-2341234".
Doesn't matter does it? It's just an identifier, if someone wants to know more
about the user they should retrieve the user profile.
I want to ping jboss.org guys and see if they allow changing or setting
usernames for their social login or how they handle that scenario.
Some sites lets users change their username, others don't. Without using the id of a
user in the token we can't support applications that do want to let users change their
passwords
BTW Google, Twitter, Facebook and GitHub all have a ID on a user as well as a
username/login name.
In the future I think we should support various scenarios to accommodate what users of
keycloaks needs are:
* No username, users can only login with email
* Allow changing username
* Don't allow users to change username
