Except that a "TLD table inheritance system" is impossible in a
DNS in which it is not, in the general case, possible to tell
which TLD a label is actually part of and in which a given node
can be effectively a subtree of multiple trees.

Nope.   I've advocated giving registries (at all levels) maximum
flexibility to determine local needs _within_ constraints
imposed by the protocols to make DNS-based identifiers in the
global Internet work well, smoothly, and as unambiguously as
possible.  And I believe I've been consistent about that for at
least the last 15 or 20 years.

No, actually, some of the "Rich people" who want those domains
would undoubtedly like the freedom to do whatever they like,
even to use character coding systems other than Unicode.  So you
need a different conspiracy theory and/or source of innuendo.

3869 doesn't discuss "development priority".  It discusses
relatively long-term research priorities.   If you would like to
put IDNs into that category and accept the five or ten year wait
it would imply, I'm sure I can find people who would be
sympathetic to that idea.  But I'm not one of them and I suspect
that few participants in the WG are either.

I wish I had a better idea what you are talking about and
whether it was relevant to the WG.
