I did not play around with actual renderers, but in theory the renderer
should be able to get the diagram out of the order of the stops, regardless
of the role. If one stop is twice in the route relation it should be obvious
that it has to be some kind of loop. So in theory forward_stop and
backward_stop can be replaced by the role stop.
In theory data users should be able to do without roles at all (though
they might appreciate some help if there are a lot of
direction-specific stop names), and data users should be encouraged
not to depend on them.
I think the simplified advice is that roles aren't required (but
that if you want to make the line-diagram service work with a
two-directions relation, then - for the moment - you need to do xyz).
Can anyone point me to a route relation with platform stop members,
so I can check how the line-diagram service works in that situation?
