They chose to make totally new inferior LC3 codec though.
Also, on my system (Android phone + BTR5/BTR15 Bluetooth DAC + Sennheiser H600) all options sound realy crappy compared to plain old usb, everything else is the same. LDAC 990kbps is less crappy, by sheer brute force. I suspect it's not only codec but other co-factors as well (like mandatory DSP on phone side)
