Of course it *could* ;)
Problem is that I have the impression that there are a number of
non-compatible uses of all sorts of roles with regard to relations
(forward/backward, or even north/south/east/west in the US) and I am
unsure if this can be handled generally. Some people seem to use
"backward" as "this way has to be reversed to form a linestring with the
others", while others seem to use "backward" as "the bus only uses this
section of road on the return journey".
But I have not systematically looked into this. Someone should perhaps
do that. - Most route relations are probably not directional (cycle
routes come to mind).
