I'm no expert on Xorg, but I'm not sure why the Xorg server requires any
drivers. While this is certainly the most common use case, is this
really a hard requires? This looks to be a nasty dependency loop.

Every single driver package requires xorg-x11-server-Xorg. RPM should
never remove it before all the driver packages are gone.

Even still, erase ordering is not properly implemented in any shipping
version of RPM. This rule is designed to aid such code if it is ever
written.
