You're right: it is meant to be tinkered with! Reading this [0] was one of the most encouraging pieces of documentation I've read in a long time: "Read the source. Flask’s code is written to be read; it’s documentation published so you can use its internal APIs. [...] The API docs are full of available overrides, hook points, and Signals. [...] The Flask class has many methods designed for subclassing [...] You can introduce WSGI middleware to wrap your Flask instances and introduce fixes and changes at the layer between your Flask application and your HTTP server [...] If none of the above options work, fork Flask." Even from just a software architecture perspective, I'm incredibly impressed with what Armin Ronacher has done with this project.
