Yes, being conservative is good as turning this off with older systems
(like the pathological Fedora 3 system that some kernel developers still
use for testing), would result in a non-booting box.  So if you know
that your system is "new enough", it's safe to turn off, but if you have
a doubt, leave it on to be safe.
