   Sure, it has dependency. That does not make it an _absolutely_ requirement to have a functional system. Because the dependency relationship could be broken. We already agreed on that, no?  Ex. I try to remove package bluez, and yum prompts me to remove gnome-shell, gthumb, xchat and several other unrelated useful packages.

Does that mean gnome-shell, xchat & gthumb can not function without package bluez? No. It means dependency relationship is broken.

That is why it is okay to let user remove package 'bluez'.  If it breaks something, user can still re-install bluez without much hassle _if & when_ he/she figures out that things aren't working as expected. Otherwise it's good riddance, one unwanted package less.

 I wonder why is gnome-bluetooth required by gnome-shell, it should be the other way round, no?

   Heh, and leaving users unable to remove unnecessary packages by prompting them to remove 100 unrelated useful packages is not dumb?
