These were a few straggling special cases to deal with Registry 1.0 data;
that data was removed ages ago and I just never got around to cleaning these
up. This removes them at long last.
There were also some TODOs for the same bug around better TLD extraction that
supports multi-part TLDs (though that's pretty unrelated to Registry 1.0/2.0),
so I fixed those since it turns out supporting multi-part TLDs is trivial.
