Has nothing to do with YUM.
It has to do with RPM.

If the changes in a package are significant enough, then any
existing configuration files are renamed ".rpmsave" and new
ones take their place.

If the changes are not significant enough that the existing
configuration files will work, the new ones are added with
".rpmnew".

This is how it has been for a long, long time in the RHL
world.

Now I agree you should _never_ see this out of a RHEL/CentOS
update.  That's the whole purpose of backporting changes in
RHEL/CentOS updates -- to _avoid_ this from every occurring.

But apparently it did.
