Obviously I don't speak for the community, but I'll give my two cents worth. I don't think this game really needs a "glitchless" category. I see merit for glitchless categories of games where the any% category is full of game breaking or game altering glitches and exploits, something like Earthbound or Gen 1 Pokemon come to mind.
In the standard run of this game there really isn't anything I would even consider a glitch, with the exception of falling through the floor in stage 2. The frame perfect see-saw jumps and stapler jumps are more tricks than glitches, and even if you were to ignore these tricks you can still post a very respectable time on the leaderboard. I can't see any situation where having two separate categories for this game would result in two very different runs.
