Well, everyone has different "productivity" needs. I'm productive when everything is customized for, uh, productivity. When my config files aren't overwritten by package managers and the settings aren't replaced at runtime by some-settings-daemon that I never wanted.
You must be that mythical Hacker News commenter who's proud of using default settings everywhere and not customizing anything :D
Anyway, setting up any BSD, or Arch, or even Gentoo doesn't really take "way too much time", come on.
Arch used to have an installer like that, but they dumped it in favor of the current boot-into-heavily-customized-live-environment-that's-nothing-like-the-default-installation-and-install-pseudo-manually-by-running-these-shell-scripts-in-the-proper-order-and-hopefully-you-memorized-the-handbook “installer”. I can't prove it, but I suspect they did that sheerly out of elitism, to keep the newbs out.
