X11 would have needed almost a complete rewrite. Wayland made sense. Eject the technical debt and focus on your use case. We aren't time sharing on a large central mini computer/mainframe anymore. And even then they generally are full single user systems run in parallel under a hypervisor these days. As wasteful as that might be.

But there's still occasions when you need to run a legacy application on old AIX, Irix, etc, or vax Hardware. And need a workstation. Which right now Wayland simply can't do without x.
