Interesting. Initially I chose to use helper tool to run sudo commands. After wrapping all those poorly-documented Authorization/ServiceManagement/XPC C APIs into Swift 3, I was like, sh*t, lemme just use askpass. Also, many of those APIs are deprecated in newer version of macOS and it's unclear that when Apple will remove them. That said, I can see the HUGE benefits of using launchd under the hood.
