I agree, using SDF for everything is probably not a good idea but it can be useful as a feature along with standard modeling tools. I sometimes use SDF volumes in Houdini to get that blended look. nTopology which is a specialised standalone 3D software use it for advanced 3D printing. You can do things like blend two different infill patterns. But as a webapp, it is cool looking. I'm curious how he managed to get it to work in a browser.
