Looks good. Some comments:
3. Problems associated with Special-Use Domain Names
In one of the listed "problems":
When a special-use domain name is added to the special-use domain
names registry, not all software that processes such names will
understand the special use of that name. Consequently, any such
use will result in queries for that name being sent to
authoritative servers. This constitutes an operational problem
for operators of root zone authoritative name servers.
I think it should be noted that this also creates a privacy issue for some
special-use domain names.
(Not just an operational problem for operators.)
4.1.2
last paragraph:
One point to take from this is that there is already a requirement in
RFC6762 that when stub resolvers encounter the special label,
'.LOCAL' at the top level of a domain name, they can only use the
mDNS protocol be used for resolving that domain name.
Remove "be used" near the end.
