Exactly. You're not supposed to pacman -Syu without looking. Part of your duty when you choose to install Arch is to take a few minutes every week to keep on top of what's new. Call it basic hygiene.
Yet none of the setup guides really stress this and there's no preferred method to keep up to date on things. Arch really needs a better system for making it obvious when nontrivial updates are about to happen.
