No, multihomers should (nearly) always use geo addresses, even if they 
can't be aggregated at that point. Then, when the network topology 
changes so that aggregation becomes possible, the end-users don't have 
to renumber.

Also note that there is no need to have areas of a fixed size. If you 
can't aggregate within Germany because the east and the west are still 
partitioned, you can at least aggregate at the Europe or western Europe 
level and spare the rest of the world from having to carry all German 
/48s.
