Bluetooth has gone on all the way upto v5.3 with a shit tonne of features. Meanwhile the average equipment manufacturer barely even needs v4.0 to get all their intended tasks to work. And the implementation nightmare of hardware limitation vs software/protocol limitation is absurd. Bluetooth Audio is straight up trash and the only way to get good audio is to design your own proprietary profile and not share it with anyone, which is what every major device manufacturer does.
