I think the audio jack was removed as a step toward not requiring cables at all.

You need to revisit your comment. A 3.5mm port with Bluetooth does not require cables any more than a Bluetooth-only device.

Except BlueTooth audio quality is terrible. No one is wrong to want something better, wireless or 3.5mm.

That's fine, but that has nothing to do with whether or not the presence of a 3.5mm jack makes wires mandatory. Whether or not the quality of the bluetooth stack improves with the removal of the 3.5mm jack is highly debatable.
