Update for new API's?

Is anyone keeping this project updated with all the new Greenlake API endpoints?  I see this project was last touched 2 years ago, so I find it hard to believe that it is.  It sounds like this was auto generated.. would it be hard to keep it updated w/ the autogenerator as your API's change?  Also, where do we find the OpenAPI references that the generator is basing this off of?
