Ex-Apple engineer here. I really like your implementation. A few years ago I built a similar tool to help me automate the testing of some of my native macOS apps. Being able to run multiple UI automation tests simultaneously was the big win in my case.
My only criticism is enabling telemetry by default. I'm a fan of having people opt-in.
