Create a blueprint of the OpenAPI that would help us generate useful things - client libraries, documentation, Swagger doc site etc.
If unable to directly generate backend API (assuming such a generator missing for our combination of Scala+Spring), attempt to use the generator for close combination and enhance our hand-written API manually -- by being inspired with the generator output at least.
