Finally, my Catch Can arrived

I said extreme knock will break pistons. Do you dispute this?

The others are possibilities, though techs I respect have seen it. I haven't. But the pulled timing is a reality. But you asked and I answered. I'm done with the debate on benefits. BTW, I used to do it for a living too, long time ago, but changed vocations due to physical disabilities. I can still do little things, but have to pay someone for the big jobs. Fortunately I found a shop I think is one of the best. All master certified techs with decades of experience in racing, and now building race cars. That's where the Jeep is undergoing extreme surgery right now.

Since you asked a question I will answer it and be done. I do not dispute detonation can damage pistons. The problem is you were implying the lack of a catch can cause all of this doom including detonation, leading to broken pistons.

Found some pics.

This is the old style clear cup...



This is the new style, next to the stock billet cup...



IIRC the old style was the same height as the billet cup.
