EIP Drafts Native ETH as ERC-20 System Contract

New EIP draft proposes stateful system contract at address 0x20, exposing native ETH balances via ERC-20 and ERC-2612 interfaces. Transfers move real balances, emit standard events, skip recipient code, and carry preferential gas schedule below WETH. Revives 2022 precompile idea. Open issues: gas constants, address confirmation, EIP-7702 invariant, selector collision.
