What does

Turn IPv4 off on <networkservice>.”
mean?
disable: “to stop something such as (part of) a machine, system, or ..

Well, it is obvious at this point that agreeing on how to very
gracefully getting anywhere is not working.
So the problem is not a priority or a problem at all.
If you do not have a deadline to work against, you won’t.
I give you this deadline.
Ans as we say “pick a number”; I picked dates.
For me, the costs of supporting IPv4 started 8 years ago when I went
ipv6-only to my edges.
Since shortly after that I have been paying extra to keep IPv4 alive for
the people who still haven’t moved to even DS on basic infrastructure.
So don’t blame me for you not moving.
For the past years people have been telling the world that the costs for
DS > for single stack.

Maybe? One is for saving resources, the other is for making something
go away; if you agree on the latter the former will be obsolete in a
few years and is just another extra graceful step towards the end. If
you’d prefer to have GoAway earlier and with that not need
Unavailable, then (a) the GoAway draft gives you the opportunity, and
(b) I can move the dates earlier for -01 to save you the work for
Unavailable. Even simpler.

Thanks, just that it’s not.
