You don't have to. The original proposal was for a community value
which *hinted* to the routeing policy that the originator would prefer
that return traffic went "thata way" if poossible. Those of use who
run simplistic networks (we only currently have one upstream, but
clients we help manage networks for still only have 2 to 4 upstreams)
would see this hint to the policy engine as "good enough" for most
circumstances. Those with more complex network can just ignore (and
transit on please) the communities proposed.

That's my understaning anyhow.
