I wouldn't have mentioned it if I had seen one there. :)

Having it in a downstream system but not in the authorative one strikes
me as a bad idea..

I think you missed my point here- technically we need a username which
isn't their email address, but they don't necessairly have to pick one
and, indeed, this code actually builds one for them as a
recommendation.  Given that they don't need to know their username for
logging in with Google or similar, it really could just be something
that we internally keep track of.

That does bring up a question though- does the code make sure to avoid a
conflict with an existing username in the one that's suggested?  I
didn't see that, and we should probably do that.
