I think he might have meant its a waste because the car doesn't really need a better chassis. It already had a well supported chassis and a torque arm 3 link setup has been proven to work well. Its done everything from run in the 8s in the quarter to run over 300mph on the Bonneville flats (with a stock aeroed body btw) and its been well proven in SCCA competition over the years as well. As much as I would love some shiney new designs for my 91 I can't really ever reason why I need them.
What it DOES need is more LSx swap support. There are all the parts needed to do the swap but only a handful of companies make them so they run a monopoly on the prices. We need better swap longtubes for decent prices. Nearly $1000 for a set of 1 3/4 primary/ 3" collector headers is crazy. $1200+ if you want to run 1 7/8 like I would want to. And those prices are without a midpipe..
