Chain plates on Giulietta, interesting design

Wtf??

It seems that there is one advantage to a bulkhead that crossed the beam to the other side: it would resist the opposing force vectors that are trying to fold the boat together.
I am wondering why these stainless blades were not made into complete frames that somehow tied into the longitudinal stringers.
I am sure that the engineering covers the "as new" bond between stainless, wood and so on, but for me, it would seem more robust just to continue the blades in both directions and have a continuous steel or aluminum structure up to the bars. It could be quite thin, but wide, and could resist lateral bending by being encased in glass and tabbed to the hull periodically.
I imagine that the weigh penalty would be insubstantial, as the current blades seem to cover 2/3 of the total distance.
Of course, it is not an open boat, and I realize that the deck will handle some of these loads, but if so, those loads would be transfered through the hull deck joint.
I were to build such a boat, I would want it to last a long, long time. I am sure the present construction will, but that is my impression neverless.

However, a continuous stainless steel rib wouldn't allow the hull to flex properly, and would likely become a hard spot that the fibers in the laminate would fatigue against.

Not if it was built with some clearance, and tabbed to the hull in a similar way to the current system.
Sees to me that one could build a complete grid out of aluminum or stainless, encapsulate it in glass, and have it somewhat isolated from the hull in a way that makes that grid structure support all rigging and keel loads.
That leads me to wonder exactly what the impulse loads on the rigging might be?
Perhaps someone knows, as I surmise that I may be thinking that they might be less than I am thinking they could be.
