What might be better aim is to have built in wipeout protection? In softfork scenario this would protect a majority threatening a minority with a wipeout if they do not opt in to some soft-fork consensus change. This could be partly done done by having automoated consensus critical checkpoints, for example at 100 blocks deep. Maybe there are better ways? This would in effect turn softforks into hardforks.
