• I don’t agree that semicolons would hurt it in any way, but that’s a list, a comma-separated list (of things people were saying about the time,¹ how “the period[']s noisiest authorities insisted on its being received”), which “This is not a service, avoid relying on it for testing and monitoring purposes” is not. I don’t think “Alice brought soup, Bob brought salad, and Carol brought cake” would be called a comma-splice. (The lack of an “and” in the Dickens quotation is merely asyndeton.)

    ¹ apposition, not a comma splice
