There's quite a few practical details that weren't addressed. Whats the self discharge of these caps? Sure, maybe they can hold a ton of energy in a small volume but who cares if it bleeds off in 2 hours? What's the performance over temperature? Does the capacity drop off at temperature? Does the available power drop off? A lot of conventional supercaps can even permanently age quite quickly at moderately high temperature.
