I just installed the Extension AND Wingman and in the URL redirect I saw this.
At first glance I thought it said "b*llsack" (can I say that word here?) and I'm sorry, but I didn't even do a double-take. It seemed like such a Goose thing to do.
But alas it's actually "sso-callback" which is just so...vanilla.
Anyway - is this a new feature request? I dunno.
