This is a great project. I am going to be watching this! One question: Why default to ujson? I understand that if you're always dealing with small, simple json objects it's quite fast and safe. But with larger json payloads, its performance and compatibility start to break down. I haven't touched it in the last 8 months, but I had to switch to Python's built-in json module (which is quite fast in 3.5) for compatibility when serializing and deserializing large json objects.
