A failure like this would be catastrophic generally and result in one side or the other way out of spec.

How about a factual answer. NO, they WILL not sag. Unless they completely fail, if anything, fiberglass leaf springs don't really wear out. Typical, steel spring has fatigue or even failure at 200,000 full cycles. GM wore out the test equipment testing the fiberglass springs. 2 Millon+ cycles and they gave up. The Z07 springs under my car, as I was told-they are off another Corvette, have 236K on them, I put another 3K on them so far. They don't sag a bit. Perfect as day one. Don't believe me, believe Dave McLellan its from his book.

Mine also seems too low in the front, infact the driver's side seems to sit an inch lower than the passenger side. There is no splintering visible and the front spring does not appear to have been modified to lower the car. The rear spring still had the factory bolts & bushings when I bought the car.
