Could our NNID help the NX be backward compatible without absorbing Wii U's architecture?

What exactly?

use the NNID on the old console to link the game to your account, so that when you register your current NNID on the NX you can re-downlad it on NX...

Well we basically know that. Real question what's with physical copies of Wi iU games if NX will not have hardware BC.
