For sure. And for the record: I am a big fan of rsync in other contexts. Also it was a useful start. Still, I want to move on for reasons I won't repeat here unless pushed :)

Fully agree.

At the moment the document is still very open about time lines and what can happen first. This was done this way because at the time it was not clear to me whether we could get CA (and Repository Server) operators to implement RRDP soon 'enough', and I did not want this to be a reason for RP implementers not to start supporting RRDP.

As it stands today I believe that Lacnic is the only major repository which does not support RRDP yet, and everyone else either supports or is running software which is capable. I don't believe that Lacnic is opposed, but I believe we should also be reasonable in our expectations especially given the pandemic that makes life hard across the globe.

So, in short I am quite open to a more clear plan where we ask all repositories to support first, then ask / demand RPs to prefer RRDP, and eventually - after measurements - make rsync optional and/or deprecate it completely.

I will reply to you (Randy) in person to see if we can revise the draft in time for Monday's meeting.
