Exactly the same thing is gradually happening with lights at home. In the past, light bulbs always had some variant of the standard screw-in socket because the bulbs would wear out so often; with modern LEDs, the lights last far longer so making them easy to replace is less important. At the same time, LEDs are so flexible in size and shape that forcing them into an easily replaceable form-factor is a much larger imposition. Between these two aspects, lamps without replaceable bulbs make a lot of sense from a purely practical design point of view.
