The <upgrades> feature was not indicating whether the upgrade path
is "supported" or not.  It is indicating that this release is
considered a newer version than the listed version.  This allows
applications to order releases, and will apply inheritance of settings.

In addition, even if CentOS doesn't consider in-place upgrades supported,
they are still possible.

So I don't think removing this is right.
