Explaining that a variable named "$username" contains a "username" is
not helpful. One have to read this comment first to understand that it
does not add anything to what's already obvious from the variable name
and the type.

Check it for both $wgUser and $this->user because they

If we have a central ID, in theory it should not trigger
CA failures when getting a token. However, it is, so maybe:
* This is the wrong way of checking attached-ness.
* It is somehow losing the central ID later.
or something else is going on.

Attempting to get a CentralAuth token for an unattached
user (or a user mid-attachment) throws an exception.
