For the same reason that Red Hat uses patches to back port security
updates and functionality into the kernel, httpd, and most of the
other packages in RHEL.  Introducing a version change may add/remove
functionality, may alter configuration options, may be lest tested,
etc.  The point of using an "enterprise" distro is that change is kept
to a minimum.
