My understanding is that this is small because it's a specification :). Most of the things I've seen implement it (eg. Ramda) are larger. Yes, I have a concat/minifying step, but as I mentioned, I'd love to see broader acceptance/implementation of tree-shaking. As it is, tying together fantasy-land, Ramda/mori, React, Redux all adds up very quickly (and that's without writing any business logic!).
