There's a lot of uncertainty at the moment, and it seems that no one has definite answers to these questions. Personally I'm waiting for these issues to be resolved before rolling out eddsa-jcs-2022:
- https://github.com/w3c/vc-data-integrity/issues/225
- https://github.com/w3c/vc-data-integrity/issues/231
- https://github.com/w3c/vc-di-eddsa/issues/72
It is also interesting to see whether @helge 's submission is going to be accepted or not: https://github.com/w3c/vc-test-suite-implementations/pull/11
