All valid annoyances, but I really think OP should try using another brand of Bluetooth headphones for a week just to get some perspective of how well AirPods "just work" compared to the competition. Manually having to re-pair once in every blue moon, one earbud playing while the other isn't, no automatic device switching without having to go through the Settings app everytime, A/V desync, dodgy mic quality, earbuds…
They support multiple devices, but no automatic switching, it's just a button short-cut to switch between them, works quite nicely for switching from my iPhone to my iPad and back.
