I don't understand why you say it's an extra round trip !
In my scenario I first send an authnrequest, only for authentication.
Later in the process I need the attributes, so I need to send another request.
So it won't take more time to send an AttributeQuery rather than an AuthRequest ! In both case there is the same number of RSA operations...
And in both case I can't be sure that another implementation would accept it...
So for me, those solutions are equivalent but it is more simple to use an AttributeQuery (with no modification in it, just using an unexpected binding) rather than a modified AuthnRequest (because I need to modifie the standard one).
