So this is not my experience at all from when I wrote the code. The
8723bu dongle I used for it came up just fine.

See this is the very opposite of what I have experienced. The bluetooth
driver ruins the signal when it's loaded with my dongle.

My point is this seems to be very dongle dependent :( We have to be
careful not breaking it for some users while fixing it for others.
