As discussed in discord, https://medium.com/rocket-pool/the-merge-0x02-mev-and-the-future-of-the-protocol-c7451337ec40 set the expectation that MEV would be an option. I’m comfortable requiring it for the smoothing pool now. I’m comfortable requiring it for everyone once withdrawals exist (so people that took the medium post to heart aren’t punished).
If we wait for withdrawals, it gives us a ton of time to judge if the effects are worth a rule for everyone or not.
