Hi! I just want to provide a little bit more background on the topic below – and ask the Chairs to take an action to confirm with the WG.
During the discussion resulting from my AD review of this document [1], the topic of whether the intent of the document was to replace rsync or not came up (see M16 in my review) – after some discussion we came to a way forward [2], which was to formally Update in RFC6480, RFC6481, and RFC7730 to change the mandatory to implement requirement for rsync and leave instead “a retrieval mechanism(s) consistent with the accessMethod element value(s)”. Even though this discussion happened on the sidr list, I sent a message to the WG asking for review of the changes [3]…but no reply was received. As Terry mentions below, these changes removed “the quality of a mandatory to implement retrieval mechanism”: rsync is no longer mandatory to implement, but neither is RRDP. I personally think that is ok because it also allows to more flexibility; rsync or RRDP (or anything else “consistent with the accessMethod element value(s)”), or both can be implemented as primary and/or backup. **Chairs**: Given that this is a significant change, and that the WG may have not been focused on the discussion, and that we now have a little more time given the fact that the IESG review of this document was deferred until Mar/2… Please explicitly ask the WG to review the Updates to RFC6480, RFC6481 and RFC7730. I think that a week of discussion on the list should be enough. Thanks!! Alvaro.

While I have never (ever) been enamoured by RSYNC, and I much prefer this direction on a personal level, the updates to the existing RFCs regarding RSYNC does two things. The first is it demotes RSYNC to 'just another access mechanism', and the second is it appears to remove the quality of a mandatory to implement retrieval mechanism. Am I reading that correctly? If this is intentional and has workgroup consensus so be it and onwards we move.. Initially this was written as an additional protocol, next to rsync. The idea was that rsync would be replaced altogether at some point, but the way to get there was intentionally left out of this document because we felt it should just focus on protocol. The changes you mention were made following AD review comments on 7 January. The intent as I understood it was to defer the question which retrieval mechanism is mandatory to another document, but leave the specifications generic.
