Exactly, which means that OS- or library-level searching and
sorting algorithms would need to be updated to do this.
(And rendering algorithms would have to be rewritten to force
ZWL/ZWNL to be invisible even in cases where the font fails to
do so.)
As I say, architectural changes of this sort *require* OS
and/or software updates.
