While I agree with that, I do not see a need that sport=* is always attached to a physical object.
In particular sports that are performed in a natural environment often have no sharp geographical 

Examples are areas in a lake for sport=swimming, or areas with rocks where you can sport=climbing.
Unless there is a physical barrier, like a floating line in the lake, you are not limited how far 
you want to swim, but you would not use the whole lake. Similarly, a geolocation is known for good 
climbing spots, however you don't want to tag each boulder, or they are hard to map cause GNSS is 
poor under the trees and the rocks are not visible from aerials for the same reason.

Thus the location is surrounded by the physical object, but the tag is on a separate node, such as a 
shop in a larger building.
