It would help if you thought a little more about duplicate things on the one 
position.
E.g. Service Station
could have 5 or 6 types of fuel, an address, a phone number, notes about 
ancillary services - car wash, groceries, telephone, atm machine, 
A number of these are "amenity=xxx" and if you merge the nodes you will have 
data loss, or difficulty in post-processing data if you string it all 
together.
The next category are things that are at different heights in the same 
location - a multistorey building with basement parking, ground level shops, 
upper levels offices and on the roof various aerials.
How will you merge all of those and not lose information?
