As far as I can tell the sketch-line ignores the
highway=platform/role=platform ways. I think Bonola renders because
it's a stop and a platform in the reverse direction relation:

Single-direction, the first stop (Bonola) is a platform member (no stop 
member exists for this one); all others are stop members.


Both directions rendered:

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,

A normal route with two variants in one direction:
http://78.46.81.38/api/sketch-route?1244881&1274167&1244883

A kind of ring route, but first/last tree stops are identical:
