This doesn't make sense to me. Skipping Day 1 avoids the random lynch that everyone knows is going to be town and everyone also knows that mafia is going to get a kill that night unless the doctor gets really lucky. So as it stands skipping Day 1 helps town by limiting the number of dead to probably 1 and provides the first day phase with an investigation and therfore more information.
Claiming any legitimate argument can be made about information gathering on Day 1 to me is false as no one is going to be claiming a power role unless they are very stupid or hoping they can get a protection and that mafia doesn't have a strongman. Everyone is flying blind on Day 1 and nothing is gained until the next day.
