OK, it looks as though the consensus is to leave NFKC in the options list
(though there have only been 3 people actually expressing an opinion).
However, I still do not follow your argument. I would have thought that
where there was the possibility to forbid some usage about which there was
some doubt, it was always safest to forbid it, with the possibility of
introducing it later (when the issues or requirements for it were better
understood). Whereas it is _much_ harder to forbid a usage later on when
maybe people have been actually using it for real.
