BGP communities are all the rage? I don't think this is new concept or
fad. Signaling behaviors as well as informing users of types of routes
have been around for awhile. For example, RFC1998 (Aug 1996) outlines
some of these behaviors with modifying local preference. Even Sprint
was advertising the ability to not advertise or prepend to individual
peers back in 2002

How is providing better capabilities for your customers macho? People
have been using these knobs 10 years ago and it worked then (just as
well as it works now).
