They are.  We have no DNS cops, no matter what people tell you about
ICANN.  And in fact, there are plenty of zones out there where you'll
find 8-bit labels, which turn out to be interpretable as labels made
up of UTF-8 or UTF-16 characters.  All we have is the ability to say,
"This is how you do it if you are doing IDNA2008."  We have to hope
that people play nice.  That said,

right.  So if we had a TRANSITIONAL category, then it would be natural
to say that, if you accept that character, there are some other things
you MUST or SHOULD do.  What we can't say, I think, is that your
existing zone MUST do _x_ or _y_, because then we're reaching past the
behaviour we're aiming for and into operation of existing zones.

At least, that's the sort of thing I'd expect from actual operators.
It's the sort of thing I'd have expected to say when I was an actual
operator.  I've more than once attempted to exhort the crowd over at
dnsop at ietf.org to pay more attention to this discussion, but if
someone else wants to try, right now would probably be an excellent
time to do so.
