Chilli Monster,
why is there a necessity to make any assumptions at all? The date, time,location and traffic loading as existed are irrelevant to the question that is being asked.
Let us turn the question 180 degrees. Has MikeeB done anthing wrong in making the final call? The only way that this could be a problem would be from an r/t loading point of view. If this were going to be a problem then the "professional" that the controller is should include a "to not report final" caveat to the clearance. It is, after all, a standard call.
If there is the tiniest possibility that "bothering" ATC by making the call helps to promote situational awareness for anybody involved, then I not only fail to see any harm in it, I also believe it is a small example of how double checking in aviation has promoted a safety culture of which we should all be justifiably proud.
Wheely.
