Can you please explain this further? How would ancient Vietnamese suffer
because of modern Chinese? And how nameprep affect this?

Once again, no one is proposing a new universal folding rule on Han. I did
once but I have stop my crusade already given how furtile it is. The CJK I-D
is strictly an informational purpose.

If han folding is difficult, then zVariant folding is 10x that and bring it to
infinity. (No, I am not saying it cannot be done...we done it but it is
incredible time consuming...)

Correct. "may or may not" and "stronger requirement" are the word I used. We
did not explicitly define any folding rule or mechanism.
