Surely its more time and energy trying to maintain software.opensuse.org, the package manager repos, the yast app itself and apper. We should be able to get ourselves into a situation where we only need one tool to rule them all.
In any case, Apper is not included with openSUSE (at least on my version) so would be useless for the beginner. There is not enough coherency between the various apps.
Finally, I hope we’re not becoming a recipe company like Apple is, trying to compile all the best ‘stuff’ from third parties and selling it off as their own. At least the Ubuntu and Linux Mint organisations have actually tried something new and innovative, regarding the Cinnamon and Unity environments (not that I’m a fan of Debian-based distros though).
