Maybe I should try smol instead of Tokio. I'm guessing a lot of libraries are made to fit with Tokio, but I imagine for a typical desktop app, a multi-threaded runtime is total overkill. Plus I could just run multiple runtimes if I want.

Like I suppose if I needed a blocking task that was also async, I could send that to a thread pool and then internally spawn a worker async runtime. It's a thinker.
