I support the adoption.  I'm willing to review future versions.

I have a couple of minor comments on 00:

- Regarding the first paragraph of Section 6, I've noticed RFC8198
  would have the same improvement effect.  You may or may not to
  mention it, but I'm noting it here as the draft also has a TODO
  about mentioning RFC8020 in this context.

- Also in Section 6:

   QNAME minimisation may also improve lookup performance for TLD
   operators.  For a typical TLD, delegation-only, and with delegations
   just under the TLD, a two-label QNAME query is optimal for finding
   the delegation owner name.

  It's not super obvious why it's "optimal".  Is this because it would
  be an exact match for minimized queries and the assumption is that
  an exact match is much more efficient than longest match in TLD
  server implementations?
