I learned to always, always use -w back around y2k, when my buddy taught me Gentoo. IIRC he had gotten his firewall config messed up at some point, or similar, due to forgetting that.

These days I'm still too scared of accidentally messing something up due to not passing -w, so I just do it. It's in my muscle memory after all so doesn't take much effort.
