I've seen guidance that the iss claim should not be blindly followed but should be subject to an allow list... e.g. see https://curity.io/resources/learn/jwt-best-practices/#5-always-check-the-issuer.

It seems to me that confirming the chain of trust from an installed root CA to the specified issuer merely ensures that the server is who it says it is, it doesn't mean that you should trust that server as an issuer of JWT for this system?
