For the cost of baking soda vs the impact to dumping acid into the sewer system, I'd do this as a required "just in case" step.

True enough and good point. May be good form to follow up with. Personally I have never witnessed any real further reaction beyond a relatively short period of time with or without the addition of a nuetrilizing agent, however if your dumping in a place where leaching into water systems is a possibility then I would agree that users should be taking further steps to ensure the acid has in fact been completely nuetralized. However dumping in such a location should also be avoided.
