I think it's worthwhile to be careful with words here.

I'd probably say that replacing the CA system is a non-goal, and reinventing things like DANE (or other DNSSEC applications) is probably another non-goal.  Trust frameworks for certificates (think "CA/Browser forum guidelines for EV certificates") are probably out of scope.

I don't recall any particular discussion at the workshop about certificate *formats*.  A WG could plausibly build a design for certain identity assumptions based on a JSON-basd certificate format; in that case, I'd hope they'd take a close look at the IETF JOSE WG (JSON signing).

A WG could also come up with some clever ideas based on self-signed certificates for some purposes; that, too, strikes me as plausibly in reach.

(Note that I'm trying to describe where I think plausible outer bounds might be; I'm not saying that the identity work resulting from these conversations should do any of these things.)
