I also see several problems to define the "same" concept:

* a shop that closes (bankrupt) and a new that opens afterwards. Is
this the same shop ? Is there a difference when the shop owner remains
the same?  When the products they sell are the same (I have a case of
bakery that closed and opened a few months later with new owners and a
different name in my town) ?

* What if the shop moves to a new address ? What if someone already
recorded the shop at the new location, how do we merge the IDs?

* A restaurant POI and the building it resides in are 2 different
concepts, they both need their own permanent ID. How can we
distinguish them ? How does the software knows this when someone
"joins" the POI and the building ?

* What do you do when a modern part is attached to a listed building ?
Will the building parts have permanent IDs ?

This is something you cannot solve with software alone. A human has to
try to decide what you have to do with the permanent IDs in some
(many?) cases.
