The proposal would see a regular qualifying session replace practice two on Friday with a sprint race, the grid of which to be set by Friday qualifying, filling the vacant Saturday session to decide the grid for the grand prix itself.
Although greeted with positive noises from the paddock, Wolff warned F1 to be "very careful" in how it moves forward with the changes.
"We are in a data-driven world," he said. "We simulate, and here we are talking about going live with something that hasn’t been simulated properly.
"So, I don’t think we want to block anything – it’s worth the experiment – but we need to be very careful with it, with the format that we have and with the responsibility we carry for Formula 1."
He added: "I think probably we share the mindset that we are racing purists and we know of the importance of the grand prix.
"It’s always been like that and we mustn’t dilute the attraction of that singular event happening Sunday afternoon as somehow a cornerstone of everybody’s weekend.
"Now, we have always been very reluctant to change that traditional format and I have seen some experiments in other race series where they have put in a second race on Saturday and the audiences were actually quite interested.
"Having said that, it by far didn’t have the importance and tradition like Formula 1, so we need to be really careful of how we are testing things."
