Vadim,

Trust is not transitive. The IRR provides the only mechanism currently
available to validate the contents of a BGP session and the mapping of
AS number to list of networks. If you think of the IRR as a system
that models the registration process of valid address space between
"consumer" and "seller" all the way along the chain, then it becomes a
prime tool that you can use to ensure only authorized things come
through a BGP connection. Without a validation check on the contents
of the BGP connection, you are subject to all the "diseases" that come
with transitive trust relationships.  Routing registries are, in my
opinion, the main technology we currently have to ensure safe routing
exchange.
