Just curious, maybe I'm missing something, but... aren't [SMAppService.register()](https://developer.apple.com/documentation/servicemanagement/smappservice/register()) and [SMAppService.unregister()](https://developer.apple.com/documentation/servicemanagement/smappservice/unregister()) the replacements to `launchctl load` and `launchctl unload`?
