I won't tell you to just go with it because anything can happen.
My windshield had a rock hit it some 6 years back. That chip developed into a crack that traveled across the whole windshield. I had a high deductible and no glass coverage then so drove it like that for about 5 years. Even with the crack, annual state inspections always went fine. There were a few times when we hit some really rough roads that I thought might take out the windshield but it never budged.
Again, results will vary so i'd go with what you feel comfortable doing.
