Once you get to the 5+ year timespan you start running into xG transitions, and modularity won't realistically be enough for phones to bypass those leaps (certification alone ensures that). You walked back OPs statement there as well. 5 years is very different than 10-20 years. I'd wager most think that phones designed to last 5 years is perfectly reasonable.
