I support this enhancement. We don't lose anything and gain types.

I do think we actually lose code splitting because Typescript only supports es6 imports out of the box. We might be able to continue to use require if we include a type declaration for it

Do you know of any apps that have used the code splitting features?

[bmbarker90]

I guess our apps currently do not because we got rid of the common chunk. If we were to add a vendor chunk though, we would need to figure something out. Either that, or wait for webpack 2
