For reasonable reasons in my view. The actor model is imo a great way of doing concurrency in the absence of the data race guarantee that safe rust provides at compile time. If you know you have no data races, I don't think actors give you that much. That said, some people just really like actors as a mental model and/or they want to interoperate with actor-based systems written in other languages or provide an actor substrate written in rust that will be embedded into another language perhaps? It's definitely a niche usage.
