Red Hat has announced they are depreciating Xorg already; which is a huge deal because they are almost single-handedly the only contributor keeping Xorg alive. Once they are done, work on Xorg will basically cease forever.
Considering Xorg is based on X11 which dates back to June 1984, I can’t blame them. A graphics system from 1984 is not suitable for 2023 in any capacity. Not without a ton of hacks, workarounds, and jank everywhere.
"depreciation" happens when capital investments lose value over time, often for tax purposes.
"deprecation" is when the builders of a tool want to discourage you from using the tool going forward because a better solution exists.
The latter is the one that applies to software.
So, yes, there's striving to a Wayland, post-X11 future, but it's far from the sure thing that X11 is.
