I would like to add deprecating rsync to the agenda. I believe it's time to move on to RRDP, and I believe that doing so will help with a number of issues regarding agenda item #1.

In particular, RRDP allows publishing CRLs and MFTs and any other updated objects, as deltas - reducing the window for inconsistent fetches. And imperfect as it may be TLS verification in HTTPS adds a layer of defence w.r.t. MiTM attacks - provided TLS verification could become mandatory.

I wrote a (straw-man?) draft about this last year, which was intended to get discussion started:
https://datatracker.ietf.org/doc/draft-sidrops-bruijnzeels-deprecate-rsync/

But I am more than happy to work with others on this. And hopefully ask for WG adoption and discussion. I am sure I am not the only one thinking about this :)
