With a macro lens there's no need to be afraid of focus breathing by making a stack of pictures with a limited range of focus-distance.

This is the point where BC has a different opinion. And me too, actually

And I don't see that as Nikon bashing, even though BC admittedly has a history of doing so. Focus breathing on macro lenses, especially modern ones (IF designs) is a given and one of the possible reasons why Nikon did not add in-camera stacking of the results.
