Because that's the only use case that was profiled. Those profiles are what
I call "dumb profiles". They exist solely to create a testable profile for
conformance reasons, and do nothing but tie a protocol to a binding. There's
no intrinsic requirement in SAML to limit bindings anywhere.

Well, I would disagree with you. That's a standard use case for SSO, so why
wouldn't you simply use an AuthnRequest?

There may be a use case for this, but I don't think yours is one.
