Yeah, that's weird, now that you pointed it out.

Userspace does nothing with the knowledge of what this specific
object's property "could" be since it's immutable. Only the kernel
internals and UAPI docs need the full list, and userspace needs to
hardcode the full list in general so it can recognize each value. But
on the property instance on a specific object, I see no use for the
full list.
