Closed hearings and a shorter confirmation process wont stop what has happened. It will just cause it to occur quicker. They were sitting on a lot of this stuff since August.
I could certainly see every President putting a “Plan B” process in place in the event a Senate confirmation battle turns into a circus. Like: “If this nomination isn’t acted upon within 60 days, I’ll put Kanye West on the Supreme Court as a temporary recess appointment.”
