I agree with the sentiment, and it would definitely make a lot of troubleshooting easier, but you do gotta remember that 99% of people are so non-technical they won't read anything going into their terminal, or if they do, they won't know what it means.
You could just as easily replace that with sudo rm -rf /* and they'd run it just as quickly, and that's my worry.
IMO we should just have settings menus alongside commands for most things any normal user might have to encounter, since that's just a more user-friendly interface in terms of preventing accidental bad command execution and also just letting people find things on their own without having to look up a command every time if they don't want to learn a short book's worth of terminal commands.
