Nothing says your shot has to be safe. Unplayable Lie has been replaced with Optional Relief (805.03c) and incurs a one stroke penalty. That will let you move to any spot on the line of play no closer to the hole.
The majority of the group cannot decide to make a new rule because they want to do so...well unless you are playing in the Legends division, they can do whatever they want...
