They need to be accurate within 3 meters vertically, and telling a first responder that a call came in from an area say 1000ft above sea level would not be that helpful to him/her when standing in front of a 45 storey building, wondering which floor they should go to.
So, it would seem knowing the floor number would be super helpful (though maybe not a regulatory requirement as you say.)
