Yes, you can do some optimizations. Keyed list diffing is obviously doable (any respectable vdom does it). Marko-style optimizations (i.e. compiling to no JS hydration logic whatsoever) is far more difficult. IIRC Dominic from the React team looked into it at some point a few years ago but it truly is a very very difficult class of optimizations to implement generically while also supporting unrestricted JS syntax.
