I'm afraid you don't distinguish "name" and "label".
Anyway, what if you encounter a label with 21 variants?
Are you saying registries MUST reject registrations requests for
domain names, if the numbeer of variants exceed 20?
Note that a single Chinese character frequently used in Japan
have, at least as I quickly checked, 6 variants, which means
your limit can easily and naturally be exceeded.
Or, how many variants, do you think, a '-' character, which
is a legal ASCII character for hostnames, have?
The idea is that the registrant simply decides which of the variants he wants to
have included with his original name. Those would be added to the zone via
redirection resource records, whatever available. When he reaches a registry
given limit, he has to make a trade-off, which of the possible variants he
regards as most valuable for his purpose. From my perspective, this is an
acceptable compromise. Otherwise, the only solution to cope with the exponential
number of variants would be to add logic about human languages and scripts
directly into the name servers that serve the respective TLD. They would have to
identify the base name, and synthesize and sign respective answers on the fly.
Besides the technical challenge, I am sure ICANN would not be pleased about this
(thinking of zone file access, escrow and the explicit ban of redirecting
unregistered names as Verisign once did, which resembles this approach).

Klaus
