Application toolkits will eventually drop support for X11. GTK will remove it in GTK5. Not sure what Qt's plans are, but I'd have to think X11 support is long for this world there as well.
GNOME is an outlier and not indicative of general trends. They pretty much do what they want, as a silo, ignoring the larger ecosystem. They want you to use their software stack all the way through.
