Started looking at Elm this weekend as a possibility for it to compile into other languages (javascript/elixir). Its too bad every release requires most packages to be rewritten. The good news is that releases are getting slower and slower, so you might go a year without any releases (even minor version patches). I guess that counts as LTS.

Elm would be so awesome if they just forked it at 0.19 and said "no more breaking releases". But I doubt that will ever happen.
