I don't read it as this wasn't tested before in R&D, but perhaps it was and gave no advantage, so was not considered. The mistake allowed them to look for other positive aspects that weren't considered before:taking the pole in circuits where the first corner is complicated and messy can be a big advantage (less risk of collision and ending the race in the same position is something good). Also making all those companies who pay a lot of money to put stickers on your car a little happier.
