I'd get it taken care of ASAP.
I bought my '92 Thunderbird Sport in Fall 2006
from the original owner who lived just a few miles up the highway where I had seen the car since new. Just below the driver's line of sight is a star chip about the size of a nickel. The lady told me it was hit by a rock flying up back some several years earlier
and that it had been repaired by SafeLite.
I had my doubts, figured I'ld have to replace it someday soon if cracks extended .... but here in 2014 it's still a sealed repair, the cracks have not extended and you cannot catch it with a finger nail. I'm convinced.
Sealing it will stabilize it, support glass edges, and prevent moisture from entering. I'ld fix it that way rather than a new WS.
