Do you not keep backups? Personally I'd prefer an exploit that trashed my homedir to one that rooted my machine, but hey, maybe I'm just weird.

It's not that exploits which only have access to your user directory aren't worth bothering about, just that exploits which only have access to your user directory are restricted in the damage they can do. Unlike on Windows, where most people web browse from Admin accounts and entire installations can be screwed from user accounts anyway.
