Why?
Most upgrades will *not* be down for an extended period of time, so
keeping the socket up is the right decision most of the time. And if it
is unexpectedly down for an extended period, the socket buffer will fill
up, and then the behavior will be roughly equivalent to if you'd taken the
socket down once the listen queue fills, wouldn't it?
It seems to me like you get basically the behavior that you want if you
leave the socket up and buffering. But maybe I'm missing something?

Why not just let the kernel do this for you?

If that was an attempt to ask someone nicely to assist you with something
that you think is important, you missed.
You have made your understanding of the problem and your belief about the
correct solution manifestly clear in this bug already. I don't think
anyone has any doubts about what you think should happen. However, it
turns out that I don't work for you, nor do the systemd maintainers, so
you might want to try for a tone more appropriate for interacting with
professional colleagues than a tone appropriate for ordering around your
subordinates.
