I would like to agree with what the Electrum Developer Thomas Voegtlin said that bitcoin unlimited is not a good idea since if we really look at the hardfork it has many bugs and it not feasible for bitcoin at this moment. But later in time if bitcoin is ready for a hardfork then maybe that will be the time that bitcoin unlimited will come into the picture.
[Bitcoin Unlimited] is a good idea, Voegtlin said - he never said he as 100% sure. "I don't think" implies one isn't 100% sure but somewhat on the fence so to speak.
