I would be okay with being "stuck" with a replacement battery and a 3.5mm jack. That's a compromise I'd be wiling to take; but at the end of the day it's all about profit.

You might be willing to, but the product might be more attractive to millions out there if they didn’t have these items. You can say that is about profit but it is also about making a better product, weighed by what customers want in aggregate.

As PP noted, the tradeoff is vs. making things thinner and more waterproof.

I'm OK with wireless charging and using the USB port for audio or other purposes, though occasionally I want to use wired Ethernet or Thunderbolt displays at the same time as wired audio, and I also use a wired charge/audio dongle as a car adapter (though there are wireless chargers available.)
