I wouldn't say it's any more unnecessary than extended shocks for the rear. Superlift could do away with the Super-ride rears and just provide shock extensions with the kit to accomplish the same thing.

A lot of people upgrade the OEM struts to get a bit firmer ride and a better damping ratio for offroading. Superlift provides longer struts in other kits, as well as most lift manufacturers. I've been lifting and offroading vehicles for a long time and I would definitely say that upgraded struts/shocks are not just a "bling" item.

Now if they would be ungodly expensive due to low demand, then I understand. But being that its pretty much a standard & affordable offering for almost every other kit on the market.... it would be nice if we had the same option; let the consumer decide how they want their vehicle to ride (some like the stock struts, a lot dont)
