I really hope Apple decides to improve things for their ecosystem within the framework of Bluetooth rather than go their own way as some people here have suggested. That route would almost certainly lead to a proliferation of proprietary PAN standards and allow cell manufacturers to tax (or just acquire) consumer audio companies, many of which are struggling to compete with AirPods already. Anyway, we're going to find out soon: Apple has all but confirmed that they're working on something to solve their Bluetooth bandwidth problem [1]. Could just be a new Bluetooth profile, and I feel for the Apple users because that would almost certainly just multiply these annoyances rather than fixing them (wider audio quality gap = more people notice when the connection is inexplicably stuck on the ultra-low quality voice call profile which happens all the time, causes the OP's Annoyance 3 and is one of the causes of Annoyance 4). But I think we'll be better off in the long run if Apple and others in the industry work on Bluetooth improvements that everyone can use without paying up to Qualcomm.
