Sitting at this IETF Hackathon, I removed IDN support from Loop. It was
implemented in a hackish way as a custom output filter anyway, that
needed per-thread state and it felt great to remove all of that. I don't
think too many people will miss it even if it were removed from BIND. I
guess BIND will hold on to it as it tries to be more of a reference
implementation.

I guess a hackathon can also be used to remove things. :)
