A long time has passed since the last major release of the X.Org X11 Xserver. Even bugfix releases have become rare. Therefore, this Change proposes replacing the nearly unmaintained upstream with a maintained fork, the X11Libre XServer.
The upstream maintainer of X11Libre had been the most active remaining contributor to the X.Org X11 Xserver before the fork. The Change Owner is well aware of the controversies around the X11Libre upstream maintainer (FreeDesktop.org CoC violations, controversial political views, conspiracy theories, rants against Red Hat), but believes that the benefit of shipping maintained software outweighs the potential annoyances when having to deal with upstream.
There is no intent to ever replace the Xwayland implementation, only the standalone Xserver and its subpackages (Xnest, Xvfb, Xephyr), and possibly the driver packages (xorg-x11-drv-*).
They’ve apparently been involved in Fedora since at least 2007 and the list of packages they maintain includes QT, so sure this isn’t some rando. Still, I doubt the backing of a low level contributor to the project will mean this proposal goes anywhere, especially the idea of replacing X11 outright when downstream packages like KDE (ironic) have indicated they won’t support it.
