What I mostly meant was that for people who prefer to use X11, that will probably remain viable for a long time, without any Wayland. There's this notion that X11 is "deprecated" and that "no one is maintaining it", but the reality of it is far more nuanced. The main "flag day" will probably be when toolkits start shifting away from X11 to Wayland only, and applications start using them (there's usually big lag between release and widespread adoption of new GTK versions and such).

Some qualified language in all of the above, because hard to predict the future etc. etc.

Or, if necessary, with just a tiny bit of Wayland; XWayland rootful mode lets you run a full X stack with Wayland as little more than a shim to the graphics driver. As a worked example, Puppy Linux implemented this: https://github.com/puppylinux-woof-CE/woof-CE/pull/2265

RedHat pushes hardest, they basically do GNOME, GNOME does GTK. So GTK will be first --my prediction-- to drop X11 support.

People that prefer X11 is not what I'd optimize for. To me X11 is deprecated, unmaintain{ed,able}. It became too much of a stumbling block for Linux and other opensource OSes. It's painful, but we have to move on. Wayland is not perfect but it seems to be doing the job lately. In two year --my prediction-- it will be more stable than X11 in all aspects.

I wouldn't either, but that doesn't mean it won't work.

both Wayland and X11 are fairly stable AFAIK. For my part I'd rather not rewrite all my X11-specific stuff. For some I probably need to have direct compositor support as you can do less with scripts, so that's not so easy. I'll probably have to spend the effort at some point, but until I don't have to: why bother?
