Miners pick up megabundles immediately if they are better than the best known block so far. It leads to significantly increased profitability (+50% MEV backtested).
Relays can merge bundles and suggest them for profit switching. Miners can define a list of trusted relay addresses from which megabundles are accepted.
Bundle scoring takes into account BASEFEE mechanisms to calculate miner's revenue from bundles.

The specification of the
