With or without geoline service support, why type=route was changed to type=street here? The latter is documented as a complex relation type "to group all the elements that make up a street together" (buildings included). Here all relations appear to include only the road itself which is what type=route is normally used for.

To me it seems that type=street relations could be created in addition to type=route relations if needed. Their purpose is different, and a road without adjacent objects is still its own thing that seem to warrant an individual OSM object (this is what people, including in Wikipedia, probably expect normally if they look for a geometry of a road).

Wikimedia might consider supporting type=street but then it should supported differently from type=route, in a more complex way, as the data in nature is different.
