*It is* a security update, unless proven otherwise. "Unpredictable System Behavior" is often just a polite name for hardware vulnerability.
I also run Trusty in enterprise environment. Particularly, I run it on a mission critical secondary network server (DNS, NTP etc.) intentionally paired to a primary Xenial machine so as not to create too homogeneous environment.
