I understand the optimism that this could just be "slipped in" for
switches and later expanded to other contexts. But, as I mentioned,
even a small feature like this is bigger than it looks.

It's in the category of "credible features we might do someday" -- which
is a very long list -- but not much more than that. The features we're
working on now have been selected because they offer a more positive
cost/benefit, so we're going to do them first, but maybe we'll come back
and look at it again someday.
