Hi ! I'm currently working on a extension using did:web methods on keycloak.
However while making it and creating a did:web account on the pds, I noticed the urls were wrongly displayed showing https://keycloak.example.com:a:a instead of https://keycloak.example.com/a/a
It seems like did:web with paths are not officially supported by the Atproto specs eventhough it works wonderfully on your implementation.
But I'll close the issue nonetheless since it is more like a wonderful oversight than a proper feature.
