However, I'm expecting this will be part of Fedora 33 (not yet out), and the QXL display driver is possibly becoming optional? Within the same release of Fedora, I expect the default module list should be stable, but between releases it might not be? But, what about long-lived major releases like RHEL / CentOS? Or people who "upgrade" from the distro release to the "advanced virtualization" release (RHEL / CentOS 8)? I also would expect functionality which seems pretty default - to stay default, although perhaps it could be a weak package dependency or similar, to permit people to uninstall it? They also moved qemu-device-usb-smartcart to optional along with the already mentioned qemu-device-display-qxl and qemu-device-usb-redirect, and I believe this has happened in the past with some of the block device drivers, only I might not use them, so they might not have affected me? I think everything in the module directory is really in scope.
