To answer my own question - there appears to be nothing either at the 
kernel or user interface level that can do this - i.e. there is nothing 
to, say, limit Bluetooth to just HID devices

Which is a pity, as it's either an all or nothing with Bluetooth, which 
means we can't use Bluetooth for Wacom tablets without opening up access 
to file transfer over Bluetooth as well ...
