Screen recording was something that couldn't just be copied over from X when building wayland, because the way X does it lets any application just read any visible data from any other application with a window open. Avoiding that kind of security hole was one of the main goals of Wayland. So it took a while for screen capture to work on Wayland. I agree that it was questionable for distros like Fedora to move to Wayland before such a critical feature was working, but now it works. Because Wayland is a protocol with no canonical implementation, it is going to take a bit of time for all compositors to implement the new standard for screen capture. But gnome has implemented it, so has wlroots, and I assume KDE has or soon will. Weston is a toy compositor, not intended for serious use, so it's not surprising if it lags behind.
