Bafang bbsdh as we know it no more?

Wow, CAN bus and $115 programmer cable. That's rough. I have a decade old Bionx ebike that uses CAN bus and the official programmer was only $40. Even the DIY programming options for CAN bus like the Crumb128 and TinyCAN circuit boards are cheaper than that.
 
Couldn’t you just gut the controller and extend the phase wires to connect, say, a KT controller?
 
In my discussion with GBK... the UART Ultra (and I believe all Bafang motors) are going CANbus only for new motor by years end.
GBK told me that UART controllers and associated parts will still be available for quite a while.
