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?
