Just for entertainment value, maybe they should change the front derailleur specs by getting rid of the modern systems and go back to the 1950's versions with shifters on the seat tube or derailleur. Then tactics could involve riding up alongside someone, punching their front DR to the little ring (on flats) or big ring (on climbs), and then the puncher takes off. Then we would see lots of fist fights too whenever the puncher was caught.
... just kiding ofc, and I'm still watching. Though classics and other one day racers are becoming more interesting to me.
