You didn't just add some more badly-traced buildings.

Yet again, you dragged part of a highway a long way out of alignment, across other roads and through buildings.

OSM data consumers actually use the mapped highway network for routing. Badly drawn building=yes polygons just make the map look full, but will not be much use until someone else re-traces them accurately, adds the building type, address, etc.
