And that you will oppose to that hardfork later just like you are opposing to it now. As said I disagree that making a softfork first and then move the commitment is less disruptive (because people will need to adapt their software twice), but if the intention is to never do the second part then of course I agree it would be less disruptive. How long after the softfork would you like to do the hardfork? 1 year after the softfork? 2 years? never?
