I do not see why this needs to be held for update but that is OK. Here is the text in the RFC revision 2019-01-04 { description "Added support for multiple datastores according to the Network Management Datastore Architecture (NMDA)."; reference "RFC 8525 <https://tools.ietf.org/html/rfc8525>: YANG Library"; } revision 2016-04-09 { description "Initial revision."; reference "RFC 7895 <https://tools.ietf.org/html/rfc7895>: YANG Module Library"; } The revision date of the 2nd entry is wrong. This is not a valid revision that needs to be preserved in the future. I do not see what real tools break if the date of a previous revision is wrong. It seems like we would have noticed before 2+ years if this broke real tools. Why would changing the 2016 date be an NBC change? There is no machine usage of revision-stmt 2 - N in YANG whatsoever.
