I am really surprised this didn't kick up

i don't think frame connectors were left off to save money.If the engineers felt they were a benefit a simple change in the die could have added 2 more folds in the floor.I'm betting the stock stamping matched the strength of the unibody ahead and behind it.
As for twist, adding torque boxes would provide a gusset type re-inforcement and there is nothing so strong as a triangle, but adding frame connectors seems to be adding 2 more 2x4's to a stud wall which it seems wouldn't help much.
...i just tryin' to look at things logically.

Well, I don't know what to tell you. Do you go to the drag strip? If you do, go through the pits. See which cars have connectors and which do not. Pay attention to them as they launch, remembering which have them and which do not. You'll see a huge difference. And I'm not talking about 13 second cars either. I'm talking about the ones that can hang the hoops.

Now, I do agree with Tony on one thing. The frame rails are connected to the rockers.....and that's good. But it's still no substitute for being connected front to rear.
