By the way, the point which drove me to check the data was that the navigation system had issues with both, displaying the information and finding it in a reasonable way. The reason is exactly the split between building and address because you actually search for a certain type of building with a certain address but can only find either or. That is one reason why I don´t understand the advantage of the general split. Sometimes it makes sense but in most cases I would say it´s worse.

Personal impression.
