Perhaps the point that you are missing is that you have identified 
examples where there is a central administrator managing a database. On 
the other hand, there is no central administrator for civil aviation, it 
is all devolved to individual states.

In principle as well as technically, it would be possible to aggregate 
all the databases - although the example of "herding cats" does come to 
mind. But you have to ask the question: is it worth it?

In many ways, an MNP is a name and the mobility routing problem is to 
first register a care-of address for that name and then to provide a 
means of looking up the (care-of) address for a given MNP (name).

This is also not the only example of an IPv6 Address being used as an 
identifier rather than a locator. For example, the type 4 SRH using IPv6 
Addresses as policy identifiers.
