The extras repo are items that "do not replace" anything from upstream
(that is ... extra or added items).  But you should not install anything
unless you need it, regardless of where it comes from.  If you do need
it, then its there.

CentOSPlus is designed to contain things that "replace" items from
upstream and that is why it is not enabled by default.  And that is how
it is different than extras ... it replaces core packages.

If you do not want anything on your machine except what is rebuilt from
upstream, then you should disable extras.  However, extras should not be
any different than enabling EPEL .. they also do not add items that
replace upstream items.
