icann now has a staff of 300 and a budget of USD 100MM. this is quite
practical for them, and it's central to their remit (technical
coordination). so, i disagree with your assessment above.

hostname objects aren't the problem. "DEV" for example is not a
registered hostname in ICANN. i know from experience that there are
already great controls in place for hostnames referenced by TLD NS
records. what i'm asking for here is controls for delegations of
registered names.

note that we already know we can't demand accurate whois, accountability
of registrants, or timely removal of names used in network abuse or
criminal activities. ICANN is structurally powerless toward those
factors. that's why DNS RPZ exists (see https://dnsrpz.info/) -- we're
placing defenses at the near end which would be far more effective and
economical at the far end. i do NOT want to have to take the same
approach with NS->(AAAA|A) chains that point into
unadvertised/unreachable/local address space.

this is a great topic for ICANN SSAC to consider, similar to what they
did for search lists.
