Do you (or does anyone) have an actual example where this is the case? It may well be true but until someone has a proof there is not really an indication of a specific problem for the UTC to address.
A document showing what happens in Case A and what happens in Case B with actual glyphs would be helpful.
The current discussion is like arguing about a color that none of the participants have ever seen.
