Feature request: Return miner's committed transactions root on eth_sendBundle

[sequence-dev-1]

One of the reasons a Flashbots bundle may not be included on-chain is because of latency.

In the case where a miner has already formed block that has been sent out to its pool of hash power, then even if a bundle has the winning score it will have to wait for the commit time to expire and the miner to form a new block.

Therefore a useful piece of information is the transactions root hash at the time the miner received eth_sendBundle. If the previously committed transactions root hash is returned and it is the same that made it on-chain, then there is a very high likelihood the bundle was not included due to latency (assuming the bundle submitted did have a higher score).

How would this handle each miner having a different transaction root?

[sequence-dev-1]

I think that's the biggest question right now. Perhaps the relay could aggregate the responses from each miner and return an array of transaction roots?

Are there other ways to provide information about latency without this approach?
