1)"has-been" is a noun.

2)"It has been the best one" has nothing to do with "has-been".
3) "It has-been the best one" does not make any sense.
4) It, a has-been, remains the best one (in my eyes) makes sense.

So with a clear definition of "perfect tense" in mind, there is no chance any confusion takes place.
