We went through this a couple of years ago at INEX and ended up with a
provisioning system which allows the operator to only allow specific IRRDB
source: entries, customisable per customer. You're right that it would be
foolish to accept any IRRDB source because a lot of them are complete trash.
Otherwise, it works incredibly well for us and has stopped innumerable
prefix leaks and other silly misconfigs.
The source code is available on github.com/inex. Lots of IXPs use it in
production.
