But they didn't. So we have to deal with it. And I happen to like
corner cases that are very simple: a good place to start work.

Really? I guess we need to step back even further then so we can
agree what we are talking about. I've been talking about clients,
NTS-KE and NTPD that conform to the Proposed RFC.
Are you expanding, or contracting, that scope?

Maybe, maybe not. Since we have not designed the server, yet, we can do
what we want, within the scope of the Proposed RFC.
And I'm not sure how per-client applies to cookie lifetime and/or reuse.
Not needed, but maybe useful.

Fair enough, but that provides no guidance on the reuse in the iburst.

We have to design for ALL cases in the proposed RFC for interoperability.

Because the Proposed RFC allows for it, so some will use it. We need to
be interroperable. It may be useful for bad connections.
If you don't like the Proposed RFC, then complain to the IETF. I just
assume we are stuck with it.
