So do I! It saved me a lot of work. I started making it as a web-based react component, and I got to the part where I was doing custom bezier curves and keyframe based animation, and I was like "ah, I'm reinventing the wheel here!" So I switched. The only (possible) downside is that the addon has to be GPL3. I always intended on licensing the engine as GPL3, so it wasn't a problem for me.
