Well, they probably have an entire team of paid engineers working on it, and a business model to make additional money. Can you really blame Evan for not being as full featured as that?

OP said their team is only three people.

That's three more than Elm has. (Founder has day job)

Really? Elm is an open source project and anyone can contribute. Github shows 81 contributors: https://github.com/elm-lang/core/graphs/contributors (this is just for elm core, the compiler has its own set of contributors)

I think it's fair to criticise the release
