What's your experience using Lynx (mobile framework)?

It's been a few months since Lynx JS (https://lynxjs.org/) was open-sourced. It seems to offer a lot with regards to speed, but it doesn't use real HTML elements, and seems to cater to the React crowd.

Has anyone used it for anything serious, and what are your thoughts? How does it compare to e.g. Flutter, Ionic + Capacitor, React Native etc.?
