I think one of the major implications missing here is that it has become much harder for parents to say no to something just because they want to. Once upon a time, and even still today,  if a parent was sick of being the bad cop they could use a little white lie instead. (eg-"we can't go to Chuck-E-Cheese's because it's closed today" instead of "Mommy just really needs some downtime at the moment") If anything though I think this is a step forward, as it helps to keep dialogues honest  between parent and child and helps keep excessively authortarian parents in check.
