For me kernel warning sounds like a reasonable approach. I will change
the patch to not drop the request with error, but to issue a warning
instead. I'll also try using better email client next time.

Furthermore I believe that most tools used for both IPv4 and IPv6
routing (like iproute) do add the CREATE flag because IPv4 route
creation does require it.
