There are similar (but more basic) systems built into some retractable gear aircraft. They generally provide an audible alert if the plane appears about to land but the gear is still up.

Pilots still land gear up, even with the alarm sounding. There is (or at least was) even a public (YouTube) video of this happening from a passenger filming.

Landing a plane is not difficult (source: I’m a pilot) but there’s a lot going on. This is clearly a UI/UX issue but innovation is relatively slow in the certified market.
