I disagree on the light bulbs, but I agree on your reasoning. It's actually really useful to have lights change the white tone over the course of the day so you get cold white during the day and warm in the evening. Also that my lights can turn on minimum dimness, and the warmest they can be automatically when I turn them on in the middle of the night.

That being said, I'd much rather that light bulbs were semi-smart (i.e. have these capabilities but no wireless control) and the light switches much smarter (i.e. somehow be able to control all of the bulb features, including color through the wiring). It'd allow apps being optional.
