It's basically a hard no from me on adding a dependency that buys me next to nothing, and bloats my payload to a customers/users mobile device. In that industry, every byte counts. In backend Java/Kotlin apps? I can pay the extra money for memory usage. I cannot ask my users to do the same.
Bundlers these days are very good. Any code that isn’t used is removed with tree shaking/dead code elimination, and React can be swapped with Preact which has a lot smaller bundle size as well.
