I think this is the question where we would need a community input.
I recently tried to map various installation configurations which we have in Fedora, and got something like this.
So we have several classes of iso images: Live, Atomic, boot.iso and DVD.iso, but all of them have text mode, kickstart mode and the graphical mode included.
We don’t want to make even more iso images, but replacing some of the existing images with a “slim” remote-only version might be good.
But then which one?
Everything iso is by definition, everything 
so I am not sure removing some feature from the Everything iso is aligned with its purpose.
But maybe we can do a remote-only Fedora Server?
