That answers my question.

Each tag combination could have a wikidata link that describes what that
combination really "is". So if we make an item for combination
leisure=pitch+sport=soccer, we can put a property wikidata=Q8524[1]. That
means that someone can make a script that finds all wikidata items Q8524 on
the map. Our tags finally get a real semantic definition. That is really
exciting!

P.S. There mustn't be more than one OSM item with the same Wikidata item.
So a minimal combination of OSM tags should have the wikidata tag. For
example, in my opinion leisure=pitch+sport=soccer+surface=grass shouldn't
get the Q8524 because a pitch can have artificial grass, and it would still
be considered a football field.
