I believe the economic majority would only come to consensus, and support a hard fork as a last resort if the "glitch" was bad enough that it might change the coin supply, increase the size of blocks, etc.
Plus what exchange would list the glitchy "prefork Bitcoin" and what merchant would accept it if some miners wanted to keep mining it? Not one.
Maybe the community would support a hard fork but this is not enough. What about the miners? The main power is concentrated in China and they are not in vain released BCH. They can fully switch their power to this coin and who will then support BTC? Consensus must always be reached. The war is disadvantageous to anyone.
