no, that's unlikely, as they cannot impose the data format that is
still prominently used for all data exchange. The only thing that might
happen is that font libraries will need to do some normalization, but
maybe we are discussing nonsense here and the TTF format has some kind
of way to refer to other glyphs and combine them or something.

It does in fact. The algorithm works by determining if _between_ to code
points there is an EGC terminator.
