Most desktops today are arguably variations of the desktops we were introduced to in windows95 and OSX (v10). The colours, placement and names change but rarely does anything new show up (save for metro desktop).
With wayland and mutter/qt+ this is a great time to try out wild and out-there concepts. It's the only way to break out and really change the desktop.
I can understand peoples frustration; the desktop, after all, wraps up everything we experience when we use our machines. However I will approach this with an open mind, and I certainly hope others will do the same.
