As I said before, "the ship has sailed". RFC 7613 has been published,
and uses NFC and case preservation. It is IMHO useless to reopen this

What is broken is your analysis. RFC 7613 does not convert passwords
to lowercase. Indeed, it says exactly the opposite, which seems to
indicate that you did not read it before calling it broken:

       Case-Mapping Rule: Uppercase and titlecase characters MUST NOT be
       mapped to their lowercase equivalents.
