What happened to " Asylum Cage" used in WCW ?

Big Poppa Pump ( WCW ) had a special cage made for matches. It was like half a globe in shape and fitted inside the regular ring. The 2 wrestlers were sealed inside, no doors, no way out once the cage was lowered.

The winner ( who ever could get a pin ) could do what they wanted with the loser for about 2 mins, as there was a set of hand cuffs attached to the steel that made up the cage.

I only ever saw 1 match using it.

Would love to see WWE reuse it , as it would be really for the Hardcore fighters. It was nothing like the hell-in-a-cell or chambers that we see now. It was solid steel, no way out except after the match.
