I don't know what you're proposing concretely, but any such proposals should
be discussed after the release.

I might have misunderstood, but I interpreted Jason's message to say that
these two properties are now coupled generally, instead of them both just
having been applied to the "relevant mode line areas". Perhaps the coupling
is not so general, and is limited to the mode line as a whole, but the same
argument still applies: they should be coupled only as needed, as particular
code sees fit.

My point was that, if these two properties are now coupled in a general way,
then that is a mistake. That would represent a change from the traditional
behavior, apparently slipped in as a bug fix, and it should be pulled out,
IMO. That's all I meant to say.
