You would be reading your CFO or lawyer's summary of the important points. In this case, the only important point is probably literally just "We filed the S-1, everything went normally".

Do you use an accountant to file your taxes? Do you read the entire tax document they submit, or do you just look at their summary of "after this much in deductions, you owe this much"?

If you do read the document in full, good on you, but I assure you most people don't, in the same way that most CEOs don't read every single document the company's lawyer produces.
