It's not vague at all, they've not paywalled any new features with the Skate pass and collab zones would likely just be called collab zones in a roadmap seeing as people already call them that. EA explictly confirmed that there will be no paid tricks, no paid gameplay areas, and no pay-to-win mechanics, which is a promise they have held themselves to with no issues.
We've got a system already in the game called Community Parks, it would take significant mental effort to imagine any world where they internally swap the names of two things they've already made names for. It'd be like going to the supermarket and the oranges are called apples and vice versa.
