Looking at my build, currently Immutable takes up 139.14 KB. I only use a few things from Immutable, so it would be nice to only pay for what I use.

Proposed solution

Provide an es6 build which compiles everything down except for modules, much like react-router, reselect, redux, etc. This way, the user can rely on their module bundler to perform tree shaking to only include what is neccesary.

Would this be possible to implement?
