What gives me headaches is, that a few months later we will again have to argue and fight about the hardfork.
I guess, there won't be much fighting about that: With Segwit2x miners are signalling in bit 4, that they activate segwit once it reaches 80% and EXACTLY 3 months later the 2mb part. Miners backing out of the 2mb part risk getting orphaned blocks.
Although I can not believe any smart user is willing to run a client build by Jihan and the Shilbert guys!
You do realize, that the Segwit2x client is mainly built by Jeff Garzik and has also some commits/reviews from Gavin Andresen?
You do realize that these guys built the clients for XT, Classic, and Unlimited as well?
