Vitalik wants your ducks in a row before proceeding

All L2s should be working on (trustless, merkle-proof-based) CCIP resolvers, so that we can have ENS subdomains registerable, updateable and readable directly on L2s.
ENS is super-important, it needs to be affordable!

Seems like this CCIP resolvers is pretty important. Does anyone know what hes talking about? CCIP-what? Oh its related to CCIP-ENS? But what is CCIP-ENS? Who started CCIP-ENS and why?

Why does he want every L2 working on this? Are they all supposed to be integrating this feature?
