I think it would be interesting to see a category that requires you to collect all of the statues, cards, and peppers, but only enough gems to enter each level. Any thoughts? I might try to record a rough run at some point soon, just so we can see what it would look like.

It might be cool too to create an Any% glitchless as long as the maze skip isn't possible anymore ... (If it is .. ignore this message :D )

I don't really like the aspect of arbitrary categories, and therefore don't see a need for a leaderboard for them. That said, you are, of course, free to run any category you want.

3l3ktr0, CoI HD will 99% surely never be patched, so the Tree Skip will always be in it. It's just hard to learn at first.

You can get a good time (top 10) without tree skip, and a glitchless time is really just a bad Any% time right now, so there's not much point.

I'm very against arbtirary categories, I don't feel they add anything to the game as a speedrun but only serves to clutter up the leaderboard. That being said, you may impose whichever challenge you want on yourself, no one can tell you how to spend your time!
