Well, in PoW mining power decides on consensus. Point is in both cases of PoW and PoS should behaviour would be considered attack on the network. That would look terrible. I rather wait for Supernet release the chain.
Attack??? Not at all. NXT-based PoS allows reorg up to 720 blocks. If anybody is 'attacking' the network, is SuperNet by hijacking chain with high forging stake. Many smaller forgers should band together to force a reorg.
More forgers on more machines is healthier for the network anyway.
