going by the logic of other posts in these forums it should, any% is any%, why should it not be allowed?

Why would anyone run a glitchless in a any% category? You will never compete with any other times, and would have to list the speedrun as "glitchless" in the any% category. If that happens why not just make another category for glitchless. The "no one is running it: argument does not make sense since there is a "any% ultra nightmare" category with only 2 times in it over the past 6 months. You are telling people to make their own category within another category. Which would not work out.
