Point taken.

This, however, has the same problem. The specification of the use
of ZWJ and ZWNJ in Indic scripts is not *between* two combining
marks, but following a combining mark (halant), preceding another
base character, usually a consonant. So we don't really know what
the implications of trying to put it between two combining marks
would be -- there aren't any specifications for doing so (yet).
