It is all evry nice to desire this, but useless unless we have some
mechanism for actually making it happen. And we don't.
Take SL addresses for a minute (where the issues this way are a little
easier - LL's need to be available to a node before it actually starts
communicating on the net, which makes them very hard to deal with).
SL's have a whole bunch of bits that was decided at Yokohama, and not
clallenged on the list, will be available to be considered as part of
the SL address - easily enough for everyone to have a a unique SL
address prefix (not routable, but unique).
But actually making that happen would require a whole identifier
assignment bureaucracy, and no-one wants to actually create (yet
another) entity like that. So, instead, sites just invent their
own identifiers (perhaps in co-ordination with other sites that they
might some day want to exchange SL info with) and they're not expected
to be unique.
