That's exactly what I'm talking about. Sorry that I wasn't clear. Let
me try again with an example:

Let's say that "foo" is one of the many packages updated in 6.1.

With CR, let's say that "foo" happens to be the first 6.1 package
added to 6.0-CR.

When I install "foo" from 6.0-CR, I am now running a combination of
6.0 + a single 6.1 rpm. This combination has probably never been
tested by upstream; almost all of the upstream people installed almost
all of the new 6.1 rpms together.

I'm here posting about this issue because I'm responding to this

The fact that upstream hasn't tested these rpm combinations means that
there's risk involved.
