Remember, the entire point of a gurney tab is that it's a quick hack that can be added to the back of a wing to increase it's downforce in an emergency. They are explicitly things that are meant to be easily removable. The norm is to run without them.
Virtually every team uses a Gurney flap these days. It's an excellent tool.
In the initial stages of a race, when the car is heavy with fuel, a Gurney flap adds downforce, which mitigates some of the negative impact that load has on cornering, braking, tire wear, etc. Then, as the race progresses and the car gets lighter, the flap can be
removed once it becomes advantageous to have reduced drag instead of added downforce, or if the driver simply wants to adjust the balance of the car.
By the look of things, I think Ferrari figured out that Gurney flaps will likely be even more instrumental this year. With an eighth gear and Monza-spec gear ratios for every track, a significant mid-race drag reduction won't result in the car bouncing off the rev-limiter as it surely would with seven shorter gears; it will just keep going and going and going and...
As such, and even though they've generally been
much smaller in previous years, it's probably a good idea to use the full 20mm allowed by the regulations (3.10.1), because the bigger the Gurney, the bigger the drag reduction when it comes off. That appears to be exactly what Ferrari has done here.
