Not really. First, any inferior court can also apply the major questions doctrine -- the SCOTUS is merely the final arbiter, but presumably in many cases either there will be no case (because the Executive will preemptively go to Congress) or the Executive will accept a lower court's decision w/o having to go all the way to the SCOTUS. Second, the doctrine is pretty clear: if the impact of a regulation is politically very controversial and its impact on the economy or liberty is quite large by comparison to more mundane regulations, then it belongs to Congress.
