One more thing from my previous things - this exists:

https://github.com/rantav/flask-restful-swagger

The docs team has been working on getting a bunch of swagger stuff 
going. This might be (needs real investigation) a nice way of 
complimenting that work - and is also looking for adoption. So one could 
imagine a future where we took that direction and OpenStack offered to 
adopt the module.

Just a thought - my opinion should be considered useless.
