My reading of that text was that it was a _restriction_, not a claim
of fact.  In other words, I interpreted that text as saying that, if a
new class is invented, IDNA (if it were specified) would need to be
specified separately for that class.  

By definition, the only place domain name labels can appear is in the
NAME and RDATA fields of resource records.  It's important to
remember that the RDATA field can have subfields (as it does in the
SOA record).  I think that's clear enough from the rest of the
discussion, and because the documents already say, "You need to
understand DNS too."
