I haven't had Arch break during an update, but I always check the home page first, there are absolutely times my system would have broken during a blind update.

Arch doesn't support blind updates - it explicitly tells you to always check the home page before an update in case "out-of-the-ordinary" user intervention is required. https://wiki.archlinux.org/title/System_maintenance

Basically, don't run arch unless you're willing to be a Linux system admin.
