Undoubtedly Wayland is the way forward and I think it's a good thing. However I wouldn't piss all over X because it served us well for many years. My LMDE 6 still runs X and probably will for the next 2 years at least because both the Mint Team and Debian team don't rush into things. They are taking it slow, testing Wayland to make sure no-one's system breaks when they switch to Wayland.
This is the best approach. Eventually it will all be Wayland but I never understood why this is such an issue. Like any tech it's progress, no need for heated debates. It's just a windowing system after all.
