Yes, and no. The need relates to protocols that depend on PKIX. RFC 8122 is "Connection-Oriented Media Transport over the Transport Layer Security (TLS) Protocol in the Session Description Protocol (SDP)". So basically it is SDP, and is a product of the MMUSIC WG (in ART). Sometimes people need to identify hash algorithms with text strings. RFC 8122 (obsoletes RFC 4572) defines such a registry. No need to reinvent the wheel. There is no change to OIDs. The textual registration requires that the OIDs already be allocated for identification. The alternate plan is to draft a Standards Track RFC specifically for the purpose of making the textual registration, referring to draft-ietf-lamps-pkix-shake. That seems like unnecessary work, but I will do it if that is what is required.
