You can easily install MATE which you claimed is equivalent to GNOME 2 so "ABC" is available just fine and no digging requires since is well advertised and widely documented.
sudo yum install @mate-desktop
The "default" download is a live image cannot hold all the different desktop environments due to size constraints and this is the reason we have multiple options at http://spins.fedoraproject.org. I am not sure what more you want honestly. You seem to be arguing for the sake of it.
