Interest in Implementing JWS JSON-Serialization for SD-JWT to Support ETSI JAdES Signatures

[peppelinux]

Following the recent pull request (PR) submitted here: oauth-wg/oauth-selective-disclosure-jwt#414, there's a growing importance for JWS JSON-serialization within the context of SD-JWT.

The goal is to leverage the existing JAdES signing infrastructure available at QTSPs (Qualified Trust Service Providers), considering how to integrate ETSI JAdES signatures, which are based on JWS, within the EUDI framework.

Using SD-JWT the implementation could benefit from such integration by transitioning to a format that is more compatible with the current JAdES signer applications. Additionally, this change would lend a more "official" status to SD-JWT within eIDAS.
