There are still cases where forward/backward are useful with P2-routes.
E.g. a route with a loop and some members used twice but different
directions.

Personally, I still use forward/backward on any member of a route which
is only used in one direction and for all P2-routes as it makes it much
easier to get the direction of the route with incomplete data.
