Nah. Don’t make it complicated. Open the root zone to everyone, we don’t need suffixes anymore other than for leeches to make money. Distribute the responsibility for the root zone, kill off the pest that is the TLD industry once and for all. Domain owners can pay a uniform flat fee to IANA shared among all participating entities that keep the infrastructure up. Everyone can have their own, freely choosable TLD. Trademark holders have a right to claim, with some dispute process similar to what we have now.

It would be glorious.
