I'm not sure a collection that one person is in charge of maintaining is the best way to go. Communities organizing themselves into some kind of structure seems more in keeping with the spirit of the fediverse.
I couldn't agree more. My point wasn't super clear upon read through. I meant users can create their own groups to organize things for themselves. I guess they can share these collections of the want is there but it's mostly just an organizational thing per user in my mind. Like multireddits if you've ever used them.
