It forces some kind of modularity. Maybe that is a good thing. We don't have all features of X11 in Wayland but we also have features in Wayland that are missing in X11. I have been on Wayland for a while now and I can't say I am really suffering. There are some tings I'd like improved further but the protocol is evolving all the time. I think we'll get there. Also the decision is already made by the big distros anyways. They seem to be mostly happy.
