Apparently so. I see a few people saying that big-endian UCS-4 would be
better, but none of them claim that Internet protocols are actually
going to move in that direction.

I don't see any serious support for the ACE-now-and-forever position.

The rest of us, the UTF-8 people and the ACE-now-UTF-8-later people, all
agree that some programs are going to have to be fixed. Sendmail's
address handling should be made 8-bit-clean, for example, and cc:Mail
should allow 255-byte local parts and 255-byte domain names.

The IDN WG can and should issue an immediate warning for implementors.
