I can understand that it would currently be nigh impossible, but it does seem like something to aim for.
I mean why use power to try to keep a plane up till the last second, that is eventually going to fail at some stage anyway.
When you could save a bit of that energy, you have power if you have autopilot, and get the landing speed and angle of attack as nears possible to optimum as you approach the sea.
Then hope for the best. (ps excuse my ignorance on this subject.)
