Given Flask is not something we support yet in Nova, could we discuss on 
that during either a Nova meeting, or maybe wait for the midcycle ?

To be honest, Chris and you were saying that you don't like Flask, and 
I'm a bit agreeing with you. Why now it's a good possibility ?

Why not Routes and Paste couldn't be using also ?
See, it's a very important question, and I remember that discussing on 
Nova API v3 2 years ago was also having these kinds of discussion.
