Yes. In principle.

landuse .. for the use of the land
building .. for the style of the building
and .. amenity .. for what the feature provides.

However the subject is amenity vs shop

So for your example I would rather use

landuse=commercial .. for the use of the land
building=retail .. for the style of the building
shop=pharmacy (would be amenity=pharmacy but I would like to see that 
changed to shop) .. for what the feature provides.

Everyone does not participate in all the OSM news sources. Thus people 
are surprised when presented with stuff they had no idea of.

I don't use it. And so on . Mappers won't use stuff that they don't see 
a need for.

So what makes the changes from amenity to shop attractive?
Mappers -A more logical grouping that is easier to remember.
Editors -A more logical grouping. SO not much here.
Renders -A more logical grouping that means rendering is easier.? Same 
colours for all shops?

Yes everthing is a compromise.
Slow changes are much better than sudden ones. Give people time to adapt.
