According to Wushuo, the Uniswap V3 Fees: Factory Owner amendment jointly sponsored by Michigan Blockchain, 404 DAO and GFX Labs was rejected with a negative vote of 30M UNI (59.89%), representatives such as teemulaumhonkasalo.eth and Wintermute (wintermutegovernance.eth) All voted against. The amendment is intended to allow the DAO to make future changes to the fee mechanism. In the proposal put forward by the Uniswap Foundation, V3FactoryOwner.sol does not have the function of setting a new owner to UniswapV3Factory.sol; if the proposal is finally passed, no one will be able to change V3FactoryOwner.sol, and this is a permanent change.
