Having a delay means developers cannot quickly verify that their
stable-branch annotations correctly resulted in their patch being
applied where they wanted.

In the rare case that we have bad patches applied through the process,
we can treat it like a CI failure, where the maintainer steps in,
force-pushes the bad patches off the WIP branch, and adds annotations to
prevent automation from re-applying the commits later.
