I think it is newsworthy because it details the strengths and weaknesses of Elm in what looks like a fairly complex project. I already use and like Elm better than any other front-end framework, but if I was considering Elm as a possibility, this information would be quite useful, I think.

Definitely not the most important thing on the list, but I use Vim to code so IDE integrations mean absolutely nothing to me. I hate IDEs. To companies and teams that can't go to the bathroom without an IDE, that may be a deal breaker. Either way, it is good information to have.
