A strechted aircraft is always the most efficient one.

That is one of the problems of the A380 - it was overdesigned to be strechted later but that never happened.

Hmmm, the 737 MAX should have an IRS (Inertial Reference System) at least. It has bigger drift, therefore not suitable as the only source for long distance / time navigation. Usually it is backed up...

Elevator feel / feedback is a simple mechanical system. It is not possible to simply extend that to cover special parts of the flight envelope.

Why not? If you accidently take off w/o flaps the critical moment is when you get out of ground effect. If you manage to accelerate out of that low energy state the aircraft is perfectly flyable....

I am pretty sure it is quite abrupt on a 747 as well. Seeing videos of such landings I always thought it would rip the tires of the wheel.

Seeing all the damage to the belly of the A/C well behind the main gear they where already (barely) flying with a lot of pitch. Therefore the gear cleared the wall.
