cycleway = opposite seems not to work on Openrouteservice

I added tag cycleway = opposite to the Cassierswegel in Zedelgem Belgium on OSM ( 51.140565, 3.136513 ) wich is oneway = yes
When I plan a bicycle route in Openrouteservice the route does not use this road when the start point is in the opposite place.
Routing for pedestrian it works as supposed.

Why not use oneway:bicycle=no ?
IMHO cycleway=opposite, should only be used for special UK-cases, not for the typical situations in Belgium. see https://wiki.openstreetmap.org/wiki/Key:cycleway .
Furthermore, the routing of OpenRouteService might take a couple of days before it gets updated after your edit.

Thanks a lot.
I will try that.
