GTK4 demo applications should be hidden or disabled by default (+-on final-releases)
After installation of gtk4.2 you'll have some apps in your menu without any real use for the "normal" user.
These are
org.gtk.Demo4.desktop
org.gtk.IconBrowser4.desktop
org.gtk.PrintEditor4.desktop
org.gtk.WidgetFactory4.desktop
In GTK+3, the demo-apps where hidden by default via NoDisplay=true
switch in the desktop file. This is not the case for GTK4 demo apps.
As I can see that they might be useful for some users, it might be the best to have them also hidden by default. Another option would be to have a compile time switch to enable them(opt-in) if wanted. This would save up a tiny bit of space, but would also require a rebuild for people who want to have them.
