PC World has an article on why USB-C has not been a viable alternative for the 3.5mm audio jack. Problems with USB-C include variable handling of digital to audio conversion, incompatible SOCs inside the cable, and non-standard analog-passthrough. In short, the cables which contain computers themselves are not standardized in behavior and the author's conclusion is that mobile devices must have 3.5mm jacks until the USB-C cable technology gets sorted out enough that they become usable.

"In a world where the signal in the phone is digital, there's no downside (and a lot of advantages) to transferring the signal to the headphones digitally."
The rest of your post contradicted your first paragraph in a detailed manner!
Also, Bluetooth is a WIRELESS protocol. For a WIRED protocol extending a few feet, nothing is better than analog.
