It would be much easier for everyone if the required fields for all contact types matched the required fields of the EPP RFC; otherwise we will run into policy that is overriding RFC compliance issues and implementation problems for both the client and the server.
To me that would be the tail wagging the dog. Technology has to support policy, not vice versa.
We could adjust what fields are displayed by type in RDAP instead of in EPP. Keep the minimum fields collected consistent and compliant with the RFC and adjust what fields that are returned in the RDAP responses.
The EPDP report explicitly describes what data elements are *transferred from registrar to registry*, not what is *displayed* in RDDS. Transferring those elements would be in breach of the recommendation, even if the fields were not displayed.
