I feel like I could make an argument for both sides, and I genuinely don't know what the general consensus is here.

On one hand, it's intentionally put into the game and the developers expect their players to slide.

On the hand, it's very easily exploitable in a way that I feel the developers didn't intend.

Would like to know so I can start using this in glitchless runs, if it isn't considered a glitch that is.
