There is a new EthMagician post by @vitalik.eth on trying to formalize requirements for nodes that keep up with decentralization but also realistically help scale the network by reaching the desired throughput.
I also left some feedback on the different types of nodes I believe we need to consider: https://ethereum-magicians.org/t/formalizing-decentralization-goals-in-the-context-of-larger-l1-gaslimits-and-2020s-era-tech/23942/2
Check it out and give your feedback.
