These two are contradictory statements.

1. lit is both newer than React, and started as a fully backwards incompatible alternative to Polymer

2. Despite being acrively promoted as "not a framework just a lib" it's rapidly sucking in all the features from "fast moving js": from custom proprietary syntax incompatible with anything to contexts, a compiler, "rules of hooks" (aka custom per-dieective rules) etc.

Again, this is exactly the "fast js churn" you're talking about.
