Great question! A large portion of our infrastructure still runs on Ubuntu Precise, and so the default "supported" options for the kernel on those machines are 3.2 or 3.13. Once you're on newer releases you get 4.x support, at the very least in backports, and at that point I would definitely agree the upgrade is worthwhile.
