MRZ,
I would agree that setting bgp attributes for non-bgp route doesn't make sense, but if a filter is using the community to decide whether or not to advertise a route, then being able to set the community in the local routing table makes perfect sense.
In ROS6, if I want to create a local route and have it advertised to the rest of my network, peers, or transit providers, all we need to do is create the blackhole route for the prefix and set the community.
In ROS7, we not only have to create the blackhole route, but now we also have to create a filter to assign a community to it, effectively doubling the work (and chances to make a mistake).
IMO, MT should bring back the ability to set some BGP attributes while creating anchor routes.
