Cosmic injunctions

Not much discussion of universal injunction in Wednesday's argument in Trump v. Hawaii. The one real exchange occurred late in Neal Katyal's argument for Hawaii, prompted by Justice Gorsuch, who questioned the "troubling rise of this nationwide injunction, cosmic injunction." Gorsuch recognized that the issue was not geography, but district courts issuing a remedy "not limited to relief for the parties at issue or even a class action" and  "assert[ing] the right to strike down a -- a federal statute with regard to anybody anywhere in the world." Katyal acknowledged sharing Gorsuch's impulse, but argued that the Court should not address the issue in this case, because of its immigration context and the need to leave it to lower courts to figure out in the first instance.

I am curious whether the lack of interest in the scope of the injunction hints at where the Court will come down on the merits.
