David, are you saying the optional parameter should be a separate spec, or
that #3 and #4 are the same thing? (I disagree with both L)

I see a new, standard token and specifying the token format are orthogonal.
The PR may accept multiple proprietary token types.

if we have the parameter in the spec, then clients know to pass it along if
they see it.
