It's not immediately obvious to me how to support an open-api (or swagger) endpoint, with biff's usage of reitit, given this example: https://github.com/metosin/reitit/blob/master/examples/ring-malli-swagger/src/example/server.clj - I expect I can figure it out, but maybe someone here has done it (or understands the routing stuff better than I do), or maybe it's something best done by modifying biff?
