I see what you mean, but I think it's debatable. I'd say maintenance in
the medium term is more likely to involve identical changes to both.
And it took me quite a while of looking at one and then the other to be
certain that there really was no difference other than TRUE/FALSE, and
then that was very puzzling. But I accept your point of view, and am OK
with leaving it alone.

That sounds like a good way to go. It should only take a few minutes,
but that will turn into an hour and I need my sleep now.
