The specific question was whether or not the .to domain serves any
useful purpose (such as a TLD for the Kingdom of Tonga) -- is there
any reason to maintain it in the root servers?
It is Yet Another ISO CC TLD that is being whored out - since domains
became commodities, ISO CCs are now "national resources". Who has a
crystal ball shiny enough to see which (small) country decides to change
its name to get a "better" ISO CC? And how far out that will be?
Another lovely spin-off of pushing the mess up towards the root of
the tree, instead of down to the leaves with further specifity.
