Establishing the APM Committee

TL;DR This proposal aims to establish the Auxiliary Proposer Mechanisms (APM) Committee, which will be responsible for reviewing, approving, and maintaining the list of APMs that Lido Node Operators are allowed to use.

For Lido, Node Operators and stakers need a way to assess how these emerging tools can impact the security, economics, and operations of the protocol. With developments like Proposer-Builder Separation, preconfirmations, and advanced block markets, decentraliz...
