That's the thing, just because there is a breakage doesn't mean there isn't a way to fix it. It just becomes a cycle of breakage and repair...Arch goes through cycles of being temporarily broken and back to working just fine. This is merely the nature of rolling release (part of the reason why I am not a rolling release distro).
Naturally, if one has the skill to fix Arch, it would be of no real concern. It might be annoying, but it seems that you can overcome those temporary disruptions caused by introduced bugs
In my time of using Linux, to my knowledge, I can't recall a kernel panic. I've had my boot record break, graphics drivers simply not want to load (that was fixable, just annoying), or GNOME Display Manager crashout hard related to a memory leak. I use Ubuntu and Fedora KDE these days, at most there is an occasional bug that doesn't cause major issues. Just little annoyances that can be solved with an upcoming update or using the terminal.
