If I've heard correctly, I think the original idea behind left-hand-kick was to gain an advantage at this kind of thing. The idea was that you could kick the bike, and then your foot would be in the perfect position to bang the gear shifter into first and then you could take off for the stars right then and there, while the other riders waste time moving feet around. I don't know if that's really why they did it, but if it is, it proves that someone in a little European workshop was analyzing the problem a lot more than it was worth!
