Not because the data is not already verified but because it is not 
generally verifiable according to the rules of verifiability we have in 
OSM.  But otherwise i think you got my point here.

If that its the case for you you should be aware that url=* tags are 
generally considered a related URL to the feature in question, not a 
unique ID.  url=http://www.apple.com/ would be considered a valid url 
tag for all apple stores probably.  Previous discussion showed that 
some (though not all) mappers think wikidata tags have to be unique 
(i.e. each value only used once).

Website URLs will often be locally verifiable - either because of 
written information (shop sign, restaurant menu etc.) or - like with 
the name - by asking informed locals.
