S4 Seasons Ice Rink Theory/Speculation

I wonder about the food stalls actually. They seem new & they're open. Currently, when placing food stalls in parks, they don't actually work, right? It'd be really cool if they could update that & make sure food stalls in public lots (parks, museums, anything that isn't residential basically) always work. Cause that's kind of a pet peeve of mine that they don't :D It'd be weird making an ice skating rink & then having to hire caterers each time you visit the lot. This picture seems to at least indicate that they're working on public lots given there's no new world. So I'd love it if either they updated this (unless I missed something?) OR if they do indeed give us dynamically changing parks/public places in already existing worlds. Not sure about that though, as it could mean we'd no longer be able to edit them ourselves (ref. San Myshuno).
