I've been using Rollup for bundle size optimizations, and I believe it will work with the lodash internal packages.

Neither Rollup nor Webpack 2 will tree-shake Lodash properly. The best option at the moment is babel-plugin-lodash.

Crap. I've already banished Babel from my toolchain -- the Babel ES6 shim throws a warning in Firefox about modifying the prototype of an object, and from what I can tell that will kill or limit both V8 and SpiderMonkey optimizations from that point on.

Back to plan A: Don't use Lodash in client code unless I'm willing to use the whole thing (so that I can get the chaining optimizations, which cherry picking doesn't support anyway).

There's no hard requirement for babel-polyfill or babel-runtime.

Babel works great without shims in modern enviros (I don't use shims in my projects).
