And this is the source of our impasse. IMO (and I say this will all
due respect) your proposal is not as simple as the two defcustoms I
suggested, and it is not cleaner than just using hooks/local-vars to
set the value of character-fold-table to whatever is relevant for the
current situation.
Since we're both just stating opinions, it's unlikely this discussion
will go anywhere.

And my point is that this is too complex for user options.
Most people won't need this much generality, and the amount of time
these people will waste trying to understand this multi-option
configuration will be significant. The few who want this behavior will
be glad that we offered it, but the time it will save them (compared
to if they wrote something in elisp) will be (IMO) small compared to
the total accumulated wasted time for everyone else.
