Then you might want to haunt Nikon forums telling people how their Nikkors 70-200 VR II are no good. And to start a petition to redefine "optically superior" as "lack of focus breathing".

The Nikkor AF-S 70-200mm f2.8 VR II has been criticised for years exactly for the same thing. Under which rock have you been hiding? The Nikkor AF-S 70-200mm f2.8 FL VR no longer has that serious issue its forebear had, and is an excellent lens. So is the new Nikkor Z 70-200mm f2.8 VR, btw.

The new Canon RF 70-200mm f2.8 L IS USM does have the negative focus breathing issue the Pentax 70-200mm f2.8 has, which is its big (only?) downside, too.

And it is not about "lack of focus breathing". The Tamron 70-210mm f4, be is the rebadged "Pentax" or the Canon or Nikon version, stays close to 200mm and so has the other direction of focus breathing. Its FOV narrows towards MFD, where the Pentax f2.8 has a FOV that widens towards MFD. 

Hope to have educated you a bit.
