Wayland is still in development and the bandwagoning are the early adopters
Not to bust your chops but I'm not sure what you're implying. What isn't still in development? WordStar? X11? Mac System 7? And Wayland's initial release was 2008. That's 15 years ago. Who are these "early adopters" of which you speak anymore?
Ahh...I get it...I saw the title and thought it was about IBM's OS/2 in an "out of the box," uncustomized state, hence "Vanilla OS 2" code-named Orchid...oh, never mind already.
