I will suggest this to my colleagues and see what they think about this.
I do think that crossing landuses are everywhere, and thus it will be a very large challenge.
In my experience, crossing landuses are often just the tip of the iceberg. Apart from minor editing glitches, they can be a sign for very poorly mapped landuses that may need a complete overhaul. It’s not as easy as separating buildings. Suppressing problems with superficial fixes doesn’t help.
