That is the only name in the alpha-3 3166 list that's delegated as a
TLD, but I will admit that it could be problematic.  Fun fact: there
are enough names in .com to give 200 names to every resident of the
Comoros.

I have seen the arguments about reserving alpha-3 3166 codes and have
never seen any plausible explanation of what problem it is supposed to
solve.  Every place with a three letter code has a two letter code,
and the argument that the three letter codes are somehow more mnemonic
or better known is ridiculous.  (Quick, what are BES, COD, and TLS?)
