Well, I could have insisted on canonicalization of floating-point data but
that's so awkward that outlawing such data is a cleaner approach. Since the

Bob,
I'm not sure I understand why you say that JCS requires *almost* full
normalization. Using browsers you can generate fully compliant JCS objects
using like 20 lines of javascript/webcrypto (here excluding base64 support).
No normalization step
Anders Rundgren added the comment:
The current JCS validator is only 150 lines and does both RSA and EC signatures:

I am not a regular json user, but my impression is the format is

I was actually hoping to implement the final part of this:
