After removing old Python 2 packages, the only thing left depending on
gconf. It's obsolete, there's almost nothing that depends on it in the repos and Arch is working on dropping it soon. Some AUR packages require it, however they may still work without it.
EDIT: This would have fit in #general-discussion, I suppose. However, I decided to put it here since I couldn't have done it without a fine distro like Manjaro. Who knows how long other distros like Wibubu will keep Python 2 around.
