This is where Nintendo was held back. They wanted BC inherent in WiiU to Wii. Therefore they had to once again build off of the existing tech vs fully changing.

Why did they remove GameCube BC then? Surely keeping that would be an advantage of using the existing tech?

Same reason they removed it from Wii. They didn't want the extra costs of controller hardware ports and this late in the game, GC BC was not an issue for users. They already had Wiis.
