It depends on the reliability of the motors and how many of them there are. With electric aircraft, you could have many more engines spread along the wing (which has some benefits), so the redundancy may be enough to guarantee some power for landing. In addition, there is no 'safe' aircraft, and all of them can fall out of the sky; glide ratios don't help you if the wing breaks at the fuselage. If the motors are as reliable as the wings, then making them more critical seems reasonable.
