Is It Just Me, or Does This Look Like a Sardine Tin?

While I do understand the allure of having sleeping space for passengers for 12+ hour flights, all sleeper economy class cabin proposed by Lufthansa would make me feel like a sardine.

Truth be told, I don't see this happening, because in order to go shorter haul, pretty much anything less than 6 hours, you would have to reconfigure the interior, and there is no place to eat.
