According to ChainCatcher, Lido has released an Auxiliary Proposer Mechanism (APM) framework. Ethereum is evolving through mechanisms such as Proposer Builder Separation (PBS) and pre-confirmation, and the APM framework will help node operators adopt these mechanisms as safely as possible, balancing efficiency, rewards, and decentralization.
Additionally, LidoDAO has proposed establishing an APM committee and is about to proceed with a vote.
