awesome - seams to conclude the applicability discussion about 1271 for ERC20: ERC-1271 : Standard Signature Validation Method for Contracts · Issue #1271 · ethereum/EIPs · GitHub
Yet, Circle just extended 2612 implementation for 1271 - without extending interface: https://etherscan.io/address/0x43506849d7c04f9138d1a2050bbf3a0c054402dd#code#F19#L1
Which approach has the better adoption potential? USDC’s adjustement of 2612 or this ERC 7597?
