Hey people,

I'm trying to create a User in Mailman 3 from an existing Address. If I were using the Python interface, that would be very easy: just create the user with no address and then link the existing address to it. However, I'm using the REST interface. In mailman.rest.users.AllUser.create(), there's a try/except block which explicitely looks for this case and raises an HTTP 400 error. Looking at the test_existing_user_error() test case, it's apparently to prevent creating a user twice, which is not my use case. Are you OK if I hack the code to automatically link to an existing address while still erroring-out if the user already exist? Or would it be better to allow linking to an existing address from the REST API?

Cheers, Aurélien
