I still don’t understand the way uid is supposed to work and what attack angles it will prevent. To me, this cannot be more than a nonce since there is no relationship between the user’s identity at the IdA and at the IA.

Moreover, I don’t see what value it provides in the context of credential issuance.

We could potentially remove it after merging this PR. NB this PR is not to implement these changes. We MUST NOT for the purpose of clarity and traceablilty. We MUST implement these with separate issue number and associated PR. Not on this PR.
