I think their approach to state management using a context is limiting like a React context. Lit is working on signals, and I think signals provide poor complexity isolation for medium to large applications.

When working on front end projects in the past, maintaining code quality was a challenge. Every React project I worked on turned into a unmaintainable ball of spaghetti, regardless of how experienced myself and the other developers were.

Lit is great but unfortunately pretty much unmaintained
