I wonder if going larger and larger with chainrings increases the risk of "taco-ing" the chainring under a lot of force. This is not uncommon on road bikes with 130 BCD crank arms and chainrings combined with narrow chainrings and lightweight components. The further the chain is from the support of the chainring bolts, the more leverage it gets if the chain is off-center from the chainring.
I would assume that 10t cog might present new challenges as well.
Campy used to have 151 BCD back in the 60s, which spaced the bolts further out. Maybe it's time for that to make a comeback...or a manufacturer to simply start a new standard based on new science and trends. Or 144 BCD is fine.
