To make sure I understand your message, do you mean RPSL/IRR are not used by most of the providers? Do they really have to configure manual line by line using CLI? I heard otherwise from some other people (who might not be entirely correct :-)

Most large providers have some automated mechanism to push/pull configurations on routers on their network. Very few large providers regularly type configurations in a router CLI (although it is necessary in an emergency). However, when RIPE, ARIN, APNIC allocate a new ASN or CIDR block to some provider in the world, that change usually needs to be manually made in provider specific databases and configurations. In practice relatively few providers do that level of checking of the route announcements, which is why blackhole route announcements happen and are so difficult to fix.
