The early NSFnet one was done to configure a single backbone. Remember that EGP was the state-of-the-art. NSFNet provided last resort routing and everyone was happy. More complex registries were not needed to keep track of this even when "back doors" appeared.

In Europe the situation was not like that at all. Despite great efforts we were never blessed with a single pan-European backbone or even a last-resort routing service. This is why RIPE developed a routing registry that was capable of being useful in a general topology of indepoendent ISPs.

FYI: Lest anyone think that the PRDB was single-backbone-specific in _design_ or capability (it pretty much was in terms of data), let me note that, when Andy Adams and I rewrote the PRDB from a SPIRES DB to a RDBMS (with help from Tom Libert and Sue Hares), we explicitly designed in the ability to include data from other backbones. This was initially done to support both the T1 and T3 backbones, but it could easily have supported other backbones as well.
