It's a dumb change pushed by teams with slower pitstops under the guise of safety. Red Bull have the fastest pitstops and they haven't made a dangerous error in years, it's actually the slower teams that have made those kind of errors. I hate it, they are trying to remove the competitive aspect of pitstops which often adds a lot to the racing.
Stupid change, and you can see it in the interviews that the teams that are pushing the safety line because they are slower, it's all a play and has nothing to do with safety in the slightest.
