AS-path filtering is a perfectly reasonable thing to do.
The route server software can either prepend the RS AS, or not.
RSng peers have full control over this via their registered inet-rtr
policy.

options: aspath-trans

Unless your policy (not specifically you, John) is promiscuous,
its necessary for both "the new guy" and existing RS peers to
update their aut-num policy (and possibly import() policy in
their inet-rtr:rs-in) in order for the new routes to be proxied via
the route servers.
