It is absolutely without justification. The language of the HEROES Act allows the Secretary of Education to "waive or modify any statutory or regulatory provision applicable to the student financial aid programs under title IV of the Higher Education Act of 1965." This is not a loophole, it is the law, passed by Congress. And regardless of any foreseen impact on the economy, SCOTUS should not legislate. Otherwise, they're just an activist court.

I've been using it in the beta for a while. The new overlay is definitely the biggest improvement for me. Everything is snappier, and the new notes feature is nice. It initially didn't have the ability to show players in the same lobby as you like the old overlay (in games that supported it, like TF2). But they re-added it after some feedback.
