It's not a separate topic if we are now discussing whether to
indicate char folding in the mode-line etc.

Irrelevant to the discussion of indicating char-folding in the
mode-line.

The point is that if multiple (and many!) kinds of char folding
are available, indicating any one of them - let alone any
combination of them - in the mode-line (as a whole, let alone in
the lighter!) is problematic.  And it would not be very helpful
to have only an indicator that said whether or not there was
currently *some* char folding.
