not at all.  they have merely been focused on maintaining the
knowledge of topology by keeping routers from melting down.  and
this is not theory, we lived it.

that most schemes folk have for new topologies have not been
realistic in terms of routing table expansion, should not be taken
as isps wanting to suppress information.  that you can't holiday on
mars this weekend is not my fault.

information reduction has been is the only tool the isps have to
deal with routing bloat and weak vendor hardware.  if you would
care to suggest others, i am all ears.
