Over the past few days there have been a number of wiki edits (mainly but

the “One feature, one OSM element” principle [1], should only ever be put 
on nodes and not on building polygons. I’ve commented on an affected talk 
page without any response.

Is there any justification for these edits?

Hi, I don't see justification to edit it widely in the wiki without prior discussion, but I oppose your interpretation of this conflicting with the "one feature, one osm element" principle. In fact a shop is a different entity than a building.
Exactly, this and below, my POV.
I even say more: that a shop is an activity more than an object.
Just as an amenity, it takes place in a building or part of it.
But it can be in open air.

building=yes
shop:fishing=yes
shop:fishing:rod:rental=yes
shop.fish=no
hotel=yes

I find those constructs very understandable and, most importantly, prone to be imagined the same way by different people

The wiki should classify keys as objects or attributes.
There is a single object per OSM element (node, way, polygon, relation)
and it can have many attributes.
shop is an attribute of building (implicitly building:shop)
fishing is an attribute of shop (as it can be of wharf if my English is correct)

Some claimed that the object could be a street number.
I must say that I never saw a number represented by a rectangle.

A shop can move to another building while staying the same shop. A shop
can close and therefore vanish without the building to vanish, and a new
shop, cafe, restaurant or whatever; entirely independent from the old
shop can open in the same building later.

The building is still the same, the old one. The shop didn't change,
it's a different shop now.

On top of that a building may have offices on the first floor
additionally to the shop in the basement, or even flats or appartments -
which are possible to map as well.

Therefore yes, I see a justification for that way of tagging; but I
don't see any justification to change the wiki without broad discussion
about it.
