I'm all for Wayland - I agree with its direction and focus.
However, Wayland will take a long time to reach the maturity that X.org has had for decades, including remote support.
As a result, having both X.org and Wayland available on your disto is probably going to be the norm (and should be the norm) for a while. X.org is less "abandonware" and more "transitionware" in my opinion.
