I wonder if there is current interest in extending this feature to the username field.
The curreny behavior stops lazy users to register that should learn how to contribute and take their time to discuss.
Considering extending this feature to the username field to promote more thoughtful contributions and discourage lazy registrations.
While third-party solutions like SSO with Discourse Connect can manage this, it may also be possible to implement within Discourse.
Open to discussion on potential technical concerns or other aspects to consider.
