Tree shaking could help, but an issue is that in bigger libraries there will often be shared abstractions that wouldn't be present in a more targeted implementation. Even libraries that are well architected and have good separation of concerns.

Unless the library is a collection of independent functions like lodash, there will be some interdependency (in the name of code quality!).

Of course, (ab)using "more targeted implementations" can cause other problems, like using too many libraries for example. No silver bullet.
