Also there is a core Elm team consisting of something like half a dozen people, unless you mean a partner club of e.g. tech teams that use Elm.
I have an immense amount of respect for Evan Czaplicki for how he tries to thread the needle here and the huge amount of thought and craft he puts into the UI and UX of Elm to make it accessible. Unfortunately you can't please everyone (hell he doesn't even please me with all his decisions, the gall of him! ;)) and Elm has had its share of vocal naysayers. Elm may or may not die out, but the impact it's had on raising the bar for the UI/UX of dealing with a compiler has been IMO one of the most valuable advancements for statically typed languages in recent years.
You still can't write a generic sort function. It's not only typeclasses, there's also no module system and Evan is patronizing about it.
Not that people in open source can't be entitled, but the way Elm handles the community is awful and patronizing. Also they make too many breaking changes for me to write code in Elm.
this is a bit sad (the fact that mobs are still mobs)
in any case I wonder if they couldn't make some kind of core partner club with people that have been long and deep Elm users
