a terminal is the bare minimum you get when installing an OS (think Arch). is what gives you the power and speed to shape your workflow exactly the way you want it. running shell inside Emacs is not a bad idea, but you don’t get emacs when you install a new OS. you get a terminal that then lets you install emacs. at that point, you might as will just use the terminal.
I don't get what that has to do with my point. Arch leans into terminal enthusiasm, so it is natural that by default all they offer is a tty to install the distribution. But as most other distributions prove, this is not necessary.
