As others have said, on distributions that go for ease of use, the terminal isn’t really needed.
However, I do consider it a convenience feature even for users who are not savvy with it: You can either troubleshoot an issue by giving instructions like “Open application X, navigate to Option, open Tab, press Button, then enter Text, hit OK and repeat for each” or “copy and paste this command into your terminal”. The amount of work on both sides is likely lower plus there’s less room for error.
