There is no "just in case" when it comes to someone using outdated firmware.
It is a *given*, except for hardware that is only used in HPC and multiple
(> 2) socket servers/workstations (which might be the case here, I don't
know what processors we're talking about).

The vast majority of PC users will never update their firmware, unless the
update is automatically offered to them, and sometimes not even in that
case.
