A whimsical point: GNS

[elear]

4.2 necessary centralization and DNS cover good ground in your draft. Right now, draft-schanzen-gns exists. Here we have the PGP web of trust of naming. The value of this draft is that it attempts to provide a way around centralized authorities and is very relevant in a world where belligerent governments try to impose controls on DNS. They turn DNS on its head and make every resolver the root.

You are already hitting at one of the two weakpoints that draft has: how do you do that first rendezvous? The other weakpoint may also be worth mentioning here: without some sort of trusted introducer model, if keys are lost, that really is the ballgame. And those keys have to be properly managed. I asked the authors to undertake a thought experiment: what would it be like for FB to run GNS? You may want to touch on some of this as a complication.

I would imagine that this could be a bit of additional text in Section 5.3 (Blockchains are not magical).
