Thanks for checking it out and for the question :) I originally started in Flask. I started out using quite a number of libraries, but got a little frustrated back then when I didn't totally grok how the pieces all worked together. And Python 3 then didn't quite have the same support it does today. WSGI was simple enough to understand, so I started from there
