Yes, there are two "conflicting" information packets on the same spot, 
one is the address and one is the POI that could be rendered e.g. as a 
shop. But it's up to the rendering rules how to deal with that.
Using a distinct address node currently leads to arbitrary random 
decisions which element to draw on the map due to space collision 
detection. Having both in one icon could (but is not currently) be used 
to define rules about how to draw a shop that has an address - e.g. by 
slightly moving the house number to the bottom of the icon, or by 
rendering the housenumber on top of the icon willingly (might depend on 
the icon).

I don't see why that's more a problem in one node than in different ones 
- except that the current rendering rules don't fit here. In that your 
argumentation sounds much like a tagging-for-the-renderer-argumentation.
