Apple has researched using a keyboard that expands up out of the MacBook Pro chassis, and retracts again when the lid is closed.
Screens on laptops have always been delicate, but perhaps never more so than now with the new 14-inch MacBook Pro and revised 16-inch MacBook Pro. It's not that those are any more delicate, it's that they are so much better that the thought of damaging them is painful.
And MacBook Pro screens do get damaged. In 2020, Apple had to advise people against fitting slideable camera covers over the lens in the lid, because it was leading to cracked screens.
Similarly, in 2015, there were MacBook Pro users complaining that just closing the lid was leading to damage on the screen coating.
