Not really. To me, it sounds like a "make it work" button. The kernel
bits of Bluetooth should already have an idea of when a device is
connected, so the kernel should be able to "do the right thing".

Having options over what "the right thing" is is probably a good idea
whilst the kinks are worked out from the default behaviour, but this is
not something that should be advertised to users.
