A non-poking fun answer for you:
Glitchless doesn't have a high enough demand to warrant creating here, or even on the category extensions page.
The true way of getting a category created, is not by asking for it, but by showing there is enough demand. Run it yourself and take it seriously, and it will be put on the category extensions boards. If a lot of other people start running the category, either because you convinced them to do so, or they convinced themselves to do so, then we can look into upgrading the category from the meme boards to the main boards. This is unlikely to happen, though not impossible.
On top of that, since this is glitchless we're talking about, you/we would need to come up with a solid definition of what that means in the first place. A reason some people are poking fun so much is because they don't believe the category can exist in the first place. If one is to ask for a glitchless category, one must come up with what that means. Otherwise it's like going to the barbershop and then not telling the barber what kind of haircut you want to get.
Context has been removed on accident but S's post here explains well that any suggestions for categories shouldn't be posted without thinking about it and how it'd actually fit it on here, and whether or not it's an actual good idea.
