A few sites do, but I do not think there are many considering how hard
it is to express using RPSL a real complete configuration for a whole
network.

Since RtConfig used to be unreliable on modern Linux systems (I do not
know if the last release has been improved in this regard) I wrote my
own tool which generates as-path and prefix-list filters (and uRPF ACLs)
for customers and peers using the IRR data and local configuration files
listing the neighbors:

My opinion is that maintaining an aut-num object for the purpose of
generating your own configuration is pointless, but maintaining proper
route and as-set objects will greatly help your peers to build their
filters. (Yes, another of these situations where your actions will only
benefit the rest of the Internet and vice versa).
