it means that a RR makes a routing decision on its client's behalf, and
its best path might not be necessarily the one the clients would have
picked (especially when the decision is based on the IGP metric to the
next-hop).

yes, it's called BGP add-path, but consider the consequences of additional
state/paths to be carried on your RR-clients..
