It's a "drop everything and patch" if you have a large multi-user server where you don't completely trust all of the users. Like say in a university with a server that students can log in to, like I have just had the joy of updating (and had RHEL break ZFS on me yet again).
But yes, in most other cases no it isn't a "drop everything" exploit - but it does mean one less layer in the multi-layer security, as unprivileged remote exploits now become root-access remote exploits.
