Having seen laptops with dedicated copy/paste/undo/redo keys, I think Apple can be forgiven for not going down the function key rabbit hole: https://pomelo.shockfox.net/pub/img/powerlite.jpg
(Yes, they could have just replaced the "regular" function keys with copy/paste keys, but I feel like that would have gone over about as well as the various times they've, uh, tried to replace the function keys)
