Maybe I should answer this.  The short answer is that this can be done
entirely automatically.

When that occurs we'll have to change our build rune, of course.

Our CI system (which does bisection and stable tracking and so on)
will wants to build old versions, so it'll have to have both build
runes and look for something in-tree to tell the two methods apart.
