It is all about use case. SD cards are a bad idea for a swap heavy primary storage solution but a great solution for storing large amounts of data that you write rarely but read often - like a music, video or other media collection. Something tells me the reason they don’t appear on regular phones is similar to the reason Apple started soldering RAM onto motherboards, and many other PC makers followed. i.e. the reason they tell you is the reason isn’t the real reason.
