I think it does. But maybe the text or the presentation I did (or both) were not clear.

It currently says that rsync URIs will remain in use, because we need names. Replacing these URIs with something else that does not suggest rysnc - e.g. URNs (RFC8141) to be transport agnostic, or even https - would introduce a breaking change that will require *all* RP software to change first before any CA can start to include these alternate URI/Ns. This will make the whole thing much harder, and I am not convinced yet that that is worth is. Hence the XML NS analogy. You will see rsync URIs but they are really just name and scope (for the directories) without a guarantee that something is available.

Other than that it says that eventually the rsync repository MAY still be available. It's not a SHOULD, not even a RECOMMENDED. It simply does not forbid it and it mentions that there may still be uses for this outside of the operational validation context. In the context of RPKI validation it says clearly that it MUST NOT be depended on. However, if people here want to bury the rsync repo completely for other purposes as well then I am perfectly fine with changing that.
