I'd agree too, but I tried a generic implementation along these lines
and it was rather complex.
Firstly an actual driver would always ask for some distinguishing user
name so it knows who it's authenticating, making "username" special in
some sense. (This is why <user>username</user> is not an XML property).
Secondly a fully general authentication method is actually imperative.
