Re: The Barry Silbert segwit2x agreement with >80% miner support.
The mempool has nothing to do with it. It doesn't matter how many transactions there are, the current segwit2x code has a default block size limit of 750kB and there are no plans to change it. Miners using the default settings will (and did) refuse to mine the required >1MB block, causing the fork chain to freeze completely.
Default block size limit of 750kB is the default Core setting. Obviously miners on live chain do not use such default Core setting. There are not plans to change it because all miners on live chain are familiar with setting it to mine blocks larger than 750kB already
