Shimano changed the 'pull' ratios for 11 speed, so FD & RDs are not compatible between 10 & 11 for most road groups.
yes, but having that availability in the hub just reduces friction of the upgrade. I suppose it’s just $50 sunk into a 10s cassette if I decide a later upgrade. If I sink $100 into a cassette and long cage deraileur, I’d probably spring for it. Just thinking out loud.
