Hi Anders

As has been discussed previously, the cavage draft has multiple issues.
There are already JOSE based solutions to this problem.

I did a short unconference talk at OSW2019 about this issue, slides here
(excuse the typos):

While there was some interest in JSON canonicalisation, most people seemed
to think that using straight forward JWTs by themselves were the solution
to the problem.

We've agreed that FAPI should provide some sort of guidance in this area
and we have an open issue that I hope to get to soon on this.
