Well, that's what I can call a timely proposal. I've been working
this week on a design for sequence AMs, while considering the cases
that the original thread wanted to handle (spoiler: there are a lot of
pieces in the original patch that are not necessary, other parts are
incorrect like dump/restore), what you are trying to do here, and more
complex scenarios in terms of globally-distributed sequences. My plan
was to send that next week or the week after, in time for January's
CF.
