GNOME devs are only paid to care about GNOME. It's been this way since 2014 when they started breaking Gtk3 applications by removing gsettings the community used but they did not.
GNOME business use cases don't get people using keyboard input so they don't care. In this case GNOME business use cases don't use KDE applications so they won't care.
Search the internet for jwz cadt.
In the most cases in KDE or Kate it will only happen if you trigger the interest of a dev (if it is no fatal bug) or you can provide some patch.
