You're talking about the other side of the problem there, Russel
was talking about the subscribers of a branch, you're talking
about the publisher.
On that side there are indeed several means to address the
problem but none can be fully automated, the publisher *has* to

Already supported (modulo some known bugs I'm aware of and plan

Well, lp itself use the 'location' file trick, I don't remember

YAGNI. You still need the publisher to *do* something.
A cheap trick than can be used *today* is to make a commit with a
comment containing the new location.
But note that this doesn't address the case we're talking about
because the old branch just doesn't exist anymore so there is *no
place* where you can put a redirection mechanism in place.

Well, even when the branch still exists if the publisher does
nothing, subscribers stay in the dark... so it's not a
technological problem only.
