Actually, your review sort of came out of nowhere as this RFC 5798 BIS has already had both an early (although it was quite late) and IETF last call review. It is on the IEGG telecast on 1-4-2024. It you looked at the datatracker you would have seen this 😎

Are you suggesting any changes to the IANA Considerations text as well? As the primary author of RFC 7048, I specifically asked you to look at this.Did you miss this? Here is the current text: 

 In the "IANA MAC ADDRESS BLOCK" registry [RFC7042], IANA has assigned
   blocks of Ethernet unicast addresses as follows (in hexadecimal):

         00-01-00 to 00-01-FF VRRP
         00-02-00 to 00-02-FF VRRP IPv6



If not, there is no advantage to updating the reference.  Actually, even if the registry name and/or format is changing, there really isn’t a significant advantage to wait for the RFC7048BIS draft to publish as the two allocations in the current format.
