I guess the only issue here is that this will mark this as a valid type for defineComponent as well, right? Is there a way we can disallow that, or perhaps we could add a JSdoc comment here?

I've added a comment. I tried to extend the type exclusively for defineNuxtComponent, but this would have required copying many types from vue, as defineComponent has numerous overloads. If you have any ideas for a better approach, I am open to suggestions for improvement.
