I missed this the first time around.  Tony, first you seem to be
assuming that identifiers will be in network layer packet headers and
that packets will be delivered using them (otherwise there would be no
question of needing to aggregate "identifiers" in network layer
routing).  Neither of these assumptions is required.  Identifiers are
primarily useful for multipath management and session continuity.
Identifiers may be in the network layer, and carried in network layer
packet headers, for convenience of the endpoints, but that doesn't
mean they should be included in routing information.
