don't know, but any raising of the limit is good. The worst thing we can do IMO is just keep the limit at 1MB while transaction volume keeps growing.
I believe the consensus around core is to increase capacity to ~1.75 MB with SegWit. So the context of analyzing this proposal should be in comparing 1.75 vs 2 or 3.5 bitcoin classic +segwit... but realistically we don't have much to discuss as nothing has been formally proposed... and we are all just speculating.
