When I say "cover", I mean the userpage cover on the new website. You can customize covers if you have supporter, yes, but once that runs out, you should still be able to change it. This would work like the userpage does right now: even after your supporter runs out, you are still able to edit it, and that does not currently apply to the cover.
EDIT: "banner" -> "cover"
