Because Elm is functionally dead. Core libraries? Not updated for 2 years. Core compiler? Not updated for 7 months. It's only Evan, who is seemingly burnt out, and hasn't handed over progress to anyone else. A quick glance into the Elm community will surface this. Feel free to nerd out on an esoteric approach but all the other products coming out are generally shipping fast and bouncing approaches off each other using Next.

It's unfortunate that the current state of affairs in software engineering is that if someone doesn't merge a bugfix PR immediately, rumors of its death begin to circle.

A quick glance at the Elm Discourse or Elm Slack will surface that our community and culture is alive, well, and growing.

Evan continues to quietly work on vnext, and is presenting at Goto Aarhus in May.

I'm not interested in changing your mind in particular, and I do not wish to argue; I am merely posting this for the benefit of anyone that should see your comment.

Sometimes, shipping fast and bouncing approaches all over the place is not, as it happens, the most sane and sustainable way to create lasting software. You and others can continue along doing that; we will continue to ship our hundreds-of-thousands-of-lines-of-code Elm frontend.
