Glitchless categories are often created when a glitch is so powerful that the speedrun completely changes the game. This glitch is in no way game-breaking. New speedrun shortcuts-glitches are found every day, if we created a category for every shortcut that is found we'd be dividing the community.
With that logic, we should also create new categories that record in-game time instead of real time because old comupters might not be able to run the game as fast as new computers, making them unable to speedrun in a competitive-level.
Adding a new category here would be throwing ourselves into a rabbit hole we cannot escape from as there is always some little thing that gains you an advantage over other runners.
The leaderboard should stay the same and anyone attempting to speedrun should consider the new glitch that has been found.
