That depends on how one counts special cases. (make-string 0 0), (make-list 0 0), (vector), and (list) all have the property that (make-vector 0 0) does - that is, each call returns the same empty object each time. I imagine that make-vector was implemented to be consistent with the other functions - at least, this behavior appears to be a conscious decision rather than accidental. So it may make sense to change these functions' documentation instead of their implementation's longstanding behavior.
