Well, one of the reasons I suggested it is because I think I actually
would want that. But, of course, it would be conditioned on a variable
(disabled by default), and follow-mode would simply have to enable it.

Sure. Don't take this as me trying to push you in a different
direction. I brought it up because it sounded like it would be
simpler.
You have a better understanding of the issue and the code than I do,
don't feel obliged to try my suggestion.
