This is what i meant: if we "renumber" the old swamp space not only in RIPE
Region, we have a cleaner routing table. many of the old swamp space
"owners" are single homed, which would clean up a lot in the routing table
if they are forced to use PA space from the respective provider.

Right, see my above comment.

There should be also made some "golden networks" for the exchanges and "important"
services, like DNS. This, correctly implemented together with the vendors,
could make live easier:
- route flap dampening works together seamless with the correct
networks in "default" configurations.
- more stability
- less routes in routing table
- clear "border" of address space together with registry borders.
But again, these are only ideas from network operators.
