Mux Sub-routers and Security Middleware

Mux has great support for middlewares and OpenAPI allows for different security mechanisms on different routes.
An easy approach to this is to build a list of routes that require:
* No auth
* Token auth
* Oauth
and check in a single middleware

Right now, I think the best approach is create the three separate middlewares and create a sub router for each model, attaching the right middleware (based on the swagger file) to each route.
