    I understand that having different point values associated with the
    same screen position complicates things immensely, but do you think is
    it a catastrophe that we should avoid at all costs, and if so, why?

I don't think we should avoid it "at all costs", but in the case of
invisible text, I doubt it is that terribly hard.  The feature I added
for invisible/intangible is an example of how we can avoid it without
too much work.

      If we
    need to avoid them at all costs, the design of the bidi display should
    consider this as a constraint as early as possible.

Please do consider this as early as possible.  It mat be impossible
to avoid the problem fully, but it would be very nice to reduce the
occurrence of it.

    I think it's mainly a user confusion issue; if such a situtation
    actually made sense in the context of bidi editing (I have no idea),
    then perhaps it wouldn't be a problem there, especially if users are
    used to it from other bidi interfaces.

I agree--if users expect this, then it isn't a problem.
