I thought that manjaro-kde-21.1.4-210925-linux513.iso would contain the packages in manjaro-kde-21.1.4-minimal-210925-linux513.iso plus the packages with the extra programs to get the full Manjaro KDE experience.
To my surprise i find that the packages gnome-desktop, gnome-keyring and xdg-desktop-portal-gtk are in minimal, but not in full.
What is the purpose of those three packages? None of these packages are required by other packages according to pamac info. Removing the packages does not seem to have any detrimental effects.
