No, I don't think that's a fair way to put it. People regularly report having quite old Arch installs without stability issues. And people also regularly advice Linux newcomers not to pick Arch.

If you check their news section, it's a reasonable number of notes, 13 for last year. I think it's fair to say it seems to work well if you are willing to follow their procedure and already know what you're doing.
