Where there is a bottleneck there is Centralization. The witness feature is a bottleneck. So, this changes nothing, because Steem has always been centralized, but now it's highlighted and is harder to rationize away as many have done in the past.
As of right now, with what Sun has said on the initial announcement, this(the softfork) benefits the top witnesses. There's no evidence that this benefits the platform as a whole.
I view this as a coup by an Oligarchy to save themselves only.
I was not asked my opinion nor were the majority of stakeholders asked, so this is not a consensus and certainly cannot claim to be community supported.
My initial opinion was 180° from this, but after quite a few discussions and a bit of research my mind was changed. The witnesses should have done the same outside of their tight circles.
I'm not impressed.
