the bluez-utils depends on a working D-Bus system bus. It has no
dependency on X or anything else (besides the Bluetooth library). So if
it pulls in X related stuff then this is a fault of D-Bus or its package
and not a problem within the bluez-utils package.

No. All of them will be extended with D-Bus functionality anyway. D-Bus
is the way to go and people fighting it are on a dead end.
