Yes indeed; these changes follow the "simple 3D buildings" tagging scheme: osm.wiki/Simple_3D_buildings.

You can see the effect on sites like http://demo.f4map.com/#lat=43.0838277&lon=-89.5241878&zoom=18&camera.theta=52.448&camera.phi=0.573

(They render the natural features like grass and trees too), or https://osmbuildings.org/?lat=43.08931&lon=-89.52811&zoom=18.4&rotation=-7&tilt=36

(They render windows on buildings that have "floors" counts, to show the proper number of floors office buildings have).
