I don't get it. Are you saying that you think it's possible that someone will

I'm saying that the body that administers the root zone is not the IETF. Not
being a policy person I don't have any specific fears, but I'll observe that
the set of people who make policy that affects administration of the root zone
has a fairly small intersection with the set of people who participate in the
IETF.
(b) SINK.ARPA is a hostname whereas INVALID is not,
This is a strawman; every subdomain of .invalid, so 2606 provides something
like 36^254 invalid hostnames.
OK, so in response to your third question of whether there's a difference in
use between SINK.ARPA and LABEL-SET-OF-YOUR-CHOICE.INVALID, the difference is
that the NXDOMAIN responses for those names come from root servers, and not
from ARPA servers.
I appreciate that the set of ARPA servers and the set of root servers today are
very nearly the same, but it is a difference.
