I'd go a bit further and say that is also why Wayland in particular has struggled with adoption given the lack of anyone maintaining X and the general support of maintainers for Wayland. It was a bad sign when screenshots required major architecture changes to how a linux system was expected to run.
Still, X.org is terrible and can be reasonably called the Internet Explorer 6 of the linux desktop. At least Wayland will be easier to displace if anyone comes up with something better. This is a step forward.
