In today's network, is there anyone left who uses 1500 byte
MTUs in their core? Surely even the people with Ethernet
switches in their PoPs are now using jumbo frames. In
yesterday's Internet, encapsulation was a problem because
of the fragmentation required, but it should be a routine
thing in today's Internet where fragmentation is avoided.

If ULAs, i.e. site local addresses, need to be visible
at two disjoint locations in the network, we have the 
technical means to do this without using up global
routing table slots. The same thing applies to geographical
addresses which may sometimes need to be made visible 
in another region. We *CAN* do things at the edges
of the network without burdening the core.
