that version is adding nothing besides the block to 2mb, why we should move from core, when with segregate we will get roughly the same thing?
all those proposal are the same in the end, but some add useless stuff that aim at bring the advantage on a side instead of another
some dont like segwit.. some dont like other features either.. but the majority collectively do want 2mb.. so a version that is just a block increase is helpful.
atleast going for an option that is just 2mb makes them still part of the relaying network. then if everyone atleast upgrades to the baseline of 2mb.. then smaller amounts of people can happily do their own thing with slight changes to features as they will all be sending out 2mb blocks
and those not wanting the features can still be full nodes, giving them time to let the minority play with the features and review actual real life outcomes instead of utopian dreams of possibilities.
