Well, there's also been a bit of a chicken and egg problem here -
as no formally verifiable authoritative source for who is authorized
to originate what IP address space has ever existed, and until that
happens, you can't secure the routing system.

Fortunately, the RPKI work will address this, and some of the RIRs
are working on RPKI implementations now.  If there are ways the IRRs
can be populated using this information and non-RPKI derived
updates can be considered less preferable (whatever that means),
then we can get to a better place with the IRRs as a stop gap until
a secure routing protocol can actually be deployed.  However,
without that as a stepping stone, it's an awfully large leap from
RPKI directly into a secure inter-domain routing protocol.
