A disaster, and yet I remember reading about attempts to replace it when I was still in University, and now here I am over a decade into my career and Wayland still isn't ready for primetime, especially if you use a video card from the #1 producer of performance video cards on the planet. Small use case I guess. X lets you do forwarding over the network and maybe sometime in the 2020's Wayland will have some sort of remote desktop solution? Still waiting on that to be ironed out...

Replacing X feels like the nuclear fusion project of the Linux world, constantly receeding into the future even as it maintains its promises of fixing all our problem When It's Done(tm).

There are various solutions already available for remoting in Wayland.

GNOME: https://wiki.gnome.org/Projects/Mutter/RemoteDesktop

KDE: https://userbase.kde.org/Krfb

Sway/wlroots: https://github.com/any1/wayvnc

Generic: https://gitlab.freedesktop.org/mstoeckl/waypipe/

Web-Based: https://github.com/udevbe/greenfield

You can also still use your X11 programs remotely within Wayland, by using XWayland, which is supported by all the major implementations.

Unrelated to Wayland, there is also backend support in GTK3/4 for rendering to a web socket: https://developer.gnome.org/gtk3/stable/gtk-broadway.html
