Definitely an advocate for a wider review process (number 3). I wrote something up and implemented a PR a against the EIP process.
Proposal: Proposal: Add Ring tags to EIPs; solicit comments from Ring(s)
PR against EIP-1: https://github.com/ethereum/EIPs/pull/1725
The TL;DR is to allow a suggestion of “review tags” during Draft which would have to be conducted by relevant subgroups/rings before a move to Last Call. This means that if a proposal needs a security review, we tag it with that. If it needs an economic analysis, we tag it with that. If it needs neither, we don’t have to tag it. Let the process define the needs of the proposal, and have completion of the process actually mean something more than “well, no one has a problem with this. I guess it’s fine?”
