I love projects like this because the web is currently so complex that only hypercorps can/will pay the cost of maintaining and evolving the engines. That said, while reading the project description I became distracted by the idea of going in the exact opposite direction of simplification: drop every declarative (HTML, CSS) and make only the lower level JS and WASM APIs available. So, everything is rendered on canvas or WebXR sessions, all media playback is with WebAudio and WebRTC, and all input is via input events (KB/M/Touch), gamepad API, and WebXR Inputs. I'm pretty sure this is a bad idea and yet it also feels like a lot of fun.
