Doubtful. The Democrats like to play that game too, under Bush the Democrats refused to hold any votes for confirmations of his candidates from June 2001 to January 2003. Then, when the Republicans got a majority and began to actually hold confirmations, the remaining Democrats filibustered all confirmations until 2005 when the makeup of the house changed enough to make that too risky and they were threatened with a nuclear option.
The Republicans did not, as is sometimes said, break all norms with Garland. The played the same game that had been going on for a very long time and happened to win for once.
