It's "spurious" in the sense that you shouldn't have to know that partial functions are implemented with anonymous objects; but it's genuine in the sense that partial functions are implemented with anonymous objects.

I'm trying to remember exactly why the restriction exists (5d9cde105e); I suspect it is because we can't define an $outer pointer. But I don't think that is relevant for this case.

class Foo extends AnyVal {
  def foo = () => 0 // okay
  def bar = {case x => x} : PartialFunction[Int, Int] // should also be okay IMO
}

Yes, that's why.
