you wrote "Bluetooth communication has nothing to do with graphics ..."
and that is even more true with the bluez-utils-3.x packages since we
dropped the PIN helper which could have introduced a Python-GTK
dependency and was really pulling in unneeded packages. All
communication is done via D-Bus and this makes it language independent
and also graphical desktop independent.

You comparison between how 2.x is working and how 3.x is doing things
simply doesn't work here. Major version are meant to break things or do
things completely different.

This is not important, because you have hard (mandatory) and soft
(optional) dependency and you simply can't express these within a binary
package. You must look at the source package to see how that works.
