Yes, I understand that Xchat is not directly dependent on bluez; It is
being a victim of associative dependency, something like
bluez <= gnome-bluetooth(libgnome-bluetooth-applet.so.0) <= gnome-shell <=
libnotify.so.4 <= xchat
My original question was if this is due to a packaging error or if yum's
dependency resolving algorithm is at fault. Because with
remove_leaf_only=1, if you try to remove individual packages,
# yum remove bluez,
# yum remove gnome-bluetooth
# yum remove pulseaudio-module-bluetooth
None of them work. But if you try to remove all 3 together
# yum remove gnome-bluetooh bluez pulseaudio-module-bluetooth
Yum prompts you to remove bluez ->

Yum's behavior is absolutely correct, it even reports you reasons why it
doesn't uninstall individual packages (in general none of them is a leaf
package).
In this particular case the problem is also the circular dependency between
bluez and gnome-bluetooth [1]. At this point I'm not sure about pulseaudio-
module-bluetooth but I suspect something similar going on there.
Even though yum might handle the resolution a little better (and dnf probably
will do that, feel free to check it), the ultimate culprit here is a very poor
packaging and both dnf and yum have only a limited set of options what to do
in such cases. Usually both do the right thing, as yum did in this case.
