The reason the changing the past, law is in place, is because depending on what is being changed, will affect life heavily. I could see subtle differences that could be changed, if no negative effect, like Rumple going back in time and changing his decision in Nasty Habits, making his relationship with Bae somewhat better, but what Zelena wants to do, totally rewrites history. Rumple also revealed in season 2, that he can change someone's age. He can either turn back the clock, keep the age the same, or age someone to death. His age thing is possibly the closest thing to changing the past.
