You couldn’t reach the keys in clamshell mode. But as for why you can’t turn off the display, I suspect you can somehow.

  But why require clamshell mode? Why not allow you to use the keyboard with the internal display turned off?

    I can’t imagine it’s a popular choice or one that’s even considered by Apple. Isn’t that what a Mac Mini is for?
