Here's the thing: no one likes the idea of being a donor at tournaments. It's real bad for attendance.
I have seen some movement in codex's to deal with the threats so I am unwilling to doom all Super Heavies to purgatory. One in an army at least represents that they are rare and expensive artifices. I've come to the point of acceptance on that. When I see more than one I feel that I'm playing an apocalypse army without an answer.
Maybe I'm wrong.
