It is not in the CR repo, because it's purpose is to enable the CR repo.
 If you have to manually download it and install it (instead of using
yum) to enable the repo, then it kind of defeats the purpose for it to
be an RPM in the first place.  We could just provide the .repo file and
say to put it in /etc/yum.repos.d/

It is not in updates because updates is just that ... updates to the
packages already in base.  Updates is not the place for "Extra" packages
that we need to distribute which are not in the upstream RPMS.  That is
what extras is for...

Extras, on the other hand, is exactly for this kind of package.  It is a
package, provided by CentOS, that is not upstream ... and is not
replacing a package written by upstream.  Extras is also enabled by
default, so all that is required is to run:

yum install centos-release-cr

To get it installed and enabled.  Once installed, it is enabled and it
works from that point on.

My personal opinion is that an RPM is not even necessary for this repo
... and that all we should do is put a repo file in the repository
itself and tell people do download it ... but if we are going to have an
RPM for it, then that RPM should be hosted in the Extras repository.
