It is because it changes the way the userspace <-> kernel interface. We added a
new interface and that flag was preventing the code to use it by default, but
now that we finished to implement the new interface it will be enabled by default.

A consequence is that you'll need to use newer version of bluez, at least 4.99.
Or call the bluetooth daemon (from a pre 4.99 version) with a parameter to
disable the new interface:

$ bluetoothd -P mgmtops

Then your bluetooth will be back.
