In my opinion we can create a good canonicalization format for JSON to be used

As can be seen on this list many are skeptical so my approach would be to 
publish easy to use open source implementations.

Yes, and part of that is supplying test data like: 
https://github.com/cyberphone/json-canonicalization/tree/master/testdata
The Microsoft folks developing "Chakra" (their JS engine) already use the 100 
million reference values.


If we do that and there is real interest then we might be able to convince 
people here about the need. In line with this ambition I have done the JS and 
Java publications. This might also show there is no actual interest and then 
that is also an outcome.

Well, another part of the standards puzzle is getting early work into real 
products and services.

FWIW, I'm personally involved in a couple of efforts using clear text JSON 
signatures:
- Saturn, an open payment authorization scheme based on an enhanced "four 
corner" trust model which aims giving banks an upper hand against Apple Pay, Google 
Pay, PayPal, etc.
- Mobile ID, an open, PKI-based, multi-issuer mobile authentication and 
signature solution for e-governments.

    Note that this is not a theoretical concern, as CVE-2010-4476 and 
CVE-2010-4645 amply demonstrate, nicely underscored by the re-occurrence of the 
latter in
