Maybe I am in the minority but I’ll never need an aux jack again

There is still significant lag for bluetooth audio on both ios and android platforms. It's doesn't really impact calling, and it doesn't really impact watching video content (because they figured out how to measure that latency in real time and inject artificial delay into the video stream so that audio and video sync). But what they haven't figured out yet is the answer for bluetooth audio for gaming. When gaming, you can't arbitrarily delay the video feed so that it lines up with audio, so the bluetooth audio experience is complete dogshit for any gaming scenario. If you game, you have to use the physical cable or the constant audio lag will drive you mad.

Also, there used to be (still are) a fair number of accessories designed to work through the aux port. Examples: mobile credit card readers that connect through aux jack (like square/paypal) that are used heavily by small vendors (especially for shows/events); also things like selfie sticks that use a cable plugged into the aux jack connected to a length of wire running inside the selfie stick to a button on the end of it.

The market is starting to come up with wireless versions of these things, but the modern wireless versions now require unique ios and android versions of them when the aux-jack solution used to be platform independent.

Also, the audio quality of an aux jack is an order of magnitude superior to anything that can be piped through bluetooth....still.

I very much appreciate devices still throwing traditional aux jacks onto mobile devices. Ideally, there will be a wireless technical solution that eventually is superior, but that technology is definitely not bluetooth and we're still waiting for it to be invented and hit consumer availability.
