I'd like to start running the game but would prefer to do so without the glitches. Is there any chance of a glitchless category being added or is this game completely dead?

yes and yes But you do not need a leaderboard to START running something. If you do, then no. You won't get a leaderboard. If you have done a bunch of runs and want other people to join you to push the game, then yes, yes you can have a leaderboard.
