Yes and that's a lot of work for what would be a two-liner in JS.

Every time someone says "just make a process and a supervisor, put it elegantly in the supervisor tree, go think through the failure modes, ponder a bit about these 3 or 4 edge cases and potential race conditions, and you're done! hooray!" I get a bit grumpy.

Elixir is awesome, but there's a simplicity to a single-threaded execution model that takes away a lot of the things that make concurrency hard.
