Long routes not always possible without a middle control point

[Nate-Wessel]

Routing between start and end points is done with a shortest path. which is not always what's desired. This for example is meant to stick to the Gardiner, but deviates onto Lakeshore to save a few meters.

Having the ability to snap the middle to the Gardiner with a control point would be great, but would also necessarily add complexity to the API if the query couldn't be decomposed and then pieced back together.
