That's a valid concern. I'm concerned about the same sort of push-back.
I think we're covered because we now point to "charter motivations" in
the intro to the charter:

Readers that are new to this work should examine the motivations that
led to this charter.

Which points here:


which outlines why using only SAML doesn't accomplish what motivated the
charter in the first place (see "Problem Statement" second bullet item).
There is also a gap analysis that demonstrates the shortcomings of SAML:


So, we have a fairly detailed response for the "why isn't a SAML
assertion a verifiable claim?" question.

Based on a quick read of this:


Do you still believe that to be true?

The charter does contain the definition of a "verifiable claim" here:


However, that definition alone is not enough. One needs to understand
the greater ecosystem we're trying to build and we endeavor to point
people in that direction. It's true that a number of readers will not
follow the link or string everything together, but in those cases, we
can point to the reasons that they might object to the work.
