I think anything that can add to action at an F-1 race can really only be good overall for both the fans and the sport in general.

Pit stops always add in multiple lead changes which, while adding excitement to the overall race, and so long as every car has to adhere to the same number of stops, really has little impact in the outcome of the race.

I've loved F-1 since the 1st race I saw as a kid back in the mid 60s but at times have found races to be somewhat boring, especially in eras where the 1st car to the 1st corner went on to win the race as almost a given.

Lead changes and overtaking add a heck of a lot to the excitement of a race, any race
