Let me say this again clearly.

class -> bus BROKEN

In the case of bluetooth it would require changing /sys/class/bluetooth
to /sys/bus/bluetooth.  Which is user visible in the worst possible
way and quick google search confirmed it will break user space scripts.

Clearly, we even have a compat API for that, and nothing would break.
If needed, a bus can create compat class links. Did you even check
with the bluetooth guys, last time I talked to them, they have been
totally fine with such a change.
