No. See below.

There is still a world outside a browser yet inside the house ;).

With the new role based system there are a lot possibilities. Basically
the auth backend has access to the client object and can use like every
kind of check. I was even thinking about TLS client cert auth.
If you authenticated the client earlier already there are a lot possible
ways to go...
Yet if this is only about transmitting a username and password I would
NOT go for breaking the standard. It is this way for a good reason. E.g.
think of get parameters: they will end up on display (general term) and
e.g. also in bookmarks and that way on disk. Also there is no way for
software to detect the meaning of them so they can not handle stuff
nicely. Think of typo in password. They simply can not prompt you for a
correct one as they do not understand how to provide it.

I support this. If you want to help I'm the last one to object. Just
join on IRC and talk to us.
Have a nice day!
