Which makes it a non-starter as HTTP is a protocol. How does a

I have no way to parse or make sense of what you are trying to say.

A protocol and an API are two different things.

If its not bits on the wire or describing the state at either end then
it isn't a protocol and if it isn't a protocol it has no place in HTTP

Been there, done that. I was editor of SAML 1.0. I think I know the
range of complexity out there.

But HTTP 2.0 should not be SAML either. We have an opportunity here to
address the central problems that SAML, OpenID and OAUTH have to work
around all the time.

Nowhere near as large as the investment in HTTP and we are proposing
to change that.
