Are there any plans to merge noirbizarre/flask-restplus#465 ?

It would be awesome if it could be disabled by app config as well, since that seems to be the way most apps differ between development and production.

Maybe how flask-apispec does it would be a good way: RESTX_SWAGGER_URL and RESTX_SWAGGER_UI_URL to define the routes. When set to None, the corresponding component is disabled.
