Do you think the test vectors need to be in the document?
I’d rather leave them in a resource that directly can be used by implementers.

Well, reserved means “not available for allocation”.  I know that the term has occasionally been misused, but that is not a reason to excise it from all documents now.  These numbers are exactly as reserved as ai=28, 29, 30 are.  Not legal now, but very much available for a future standards effort if there ever is one that extends CBOR beyond its premeditated extension points.
