I’ve got a few additional topics:

1. Update mev-boost to call getPayload on _all_ relays (instead of only those which sent the bid)? ([mev-boost issue#530](https://github.com/flashbots/mev-boost/issues/530))
2. Proposer payment methods - allowing coinbase payments
3. Blind bid selection with zero knowledge proofs
