Vector Tiles are deployed on OpenStreetMap.org

The problem with “name” is that sometimes people shoehorn multiple values in there, for all sorts of valid local reasons. In Brussels’ case both names in the name tag are equally valid local values of name. Elsewhere where there is a “canonical local name” the name sometimes has other values in it, perhaps because the country is multiligual, even if the vast majority speaks one language and a small archipelago speaks the other.

Edited to add:

That looks like just the name tag and has the same issue that I described above.
