I'm not sure of how to tackle that with swagger, but maybe I should add that also in the original REST API docs (on the Graphhopper website) it's not clear...

That's great, thanks! I still find the REST API docs a bit confusing in that it's not explicitly stated what the required minimal parameters are (see e.g. [here](https://dev.twitch.tv/docs/api/reference#get-users-follows) to see...

That's great, I'll take a look at the main issues thread then. I can tell you what feels right python-wise, that is to have required or optional function parameters clearly...
