Because they are patronizing the user, relatively hard to overcome and
situations where they seem necessary should be avoided in general.

As written in the first post in this thread: since RDO strives to always be
(equal to or more likely) ahead of RHEL and EPEL, such an override should
never be necessary. And overriding "packages from _elsewhere_" should not
be considered necessary as no other repos are (nor should they be)
supported.

Like in what case? When will RDO ever want an older version of something
than what is in RHEL / EPEL?

The only thing I can possibly come up with right now are the kernel and
other tools where new networking stuff (netns, maybe more) was enabled
ahead of time but I sure hope those changes make it back into RHEL with the
next kernel update there. Or if not, that new RHEL kernels are again
re-built with those patches for RDO as well to avoid security holes.
