Exactly this, I literally was just trying to implement a simple Elixir server that would scale pretty well. The problem is the protocol is incorrectly spec-ed, is not thought through very well, is incredibly complex and hard to explain, and reinvents the wheel in just about every way it can. This means that in languages like Elixir, which has stuff like an ActivityPub implementation, OpenAPI libraries, and JSON Schema support, you have to write everything from scratch because the user base is smaller than TypeScript / whatever they're writing their implementation in. The protocols they're layering on don't have proper implementations in Elixir, because they're hard to implement right and are annoying to deal with.
