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.
This is completely clear - http://wiki.centos.org/AdditionalResources/Repositories
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.
Also clear - as i said, from here it's more a conceptual viewpoint.
What's about the maintenance policy for extras?
Thanks
