There isn't really much difference. It's about the same amount of work either way to ship an extension.

In Wayland, you make the extension, then you patch every compositor, every toolkit and every application.

In X11, you make the extension, then you patch the X server, Xlib, XCB, every window manager, every toolkit, and every application.

The question was related to the relative difficulty of replacing the whole graphics stack vs. patching in support for an X extension that has existed for longer than Wayland. One of these things is far, far less work than the other.

As someone who has done both, I respectfully disagree.

I call bullshit. If you had done so, you would have shared links to them to prove your point.

There's no code I can show you that would be any more convincing than just looking at the code to the X server and then looking at the code to any wayland implementation. There's not anything particularly special about these projects.
