Linking a bit4 MASF with a bit4 "lock in of a hard fork in 6 months" is something that will simply never happen for basic engineering reasons.
Spoonet, an oft-quoted hard fork that actually has some strong support, is a much better candidate for the code base - but not of the supposed supporters of bit4 MASF seem to be ready to roll up their sleeves and do any work at all. I mean, if they really had "millions" for development, they could just hire dome developers and built it correctly, right? But they aren't ... instead they are pumping money into "bcoin", which doesn't yet have any of the protections needed to get consensus. Maybe it will some day.
Claiming that miners support segwit is disingenuous ... considering that if they supported it, they would be signaling for it today... instead of distracting the community with fake proposals that have no peer-reviewed code.
