Nimzowitsch Defense also has a lot of theory :) and against d4, Nc6 is just a blunder. So... Nope.

It’s not a blunder, it’s a bad move but not a blunder.

e4 Nc6 is a mistake, but d4 Nc6 is a blunder.

If you analyse any game that begins with d4 Nc6 with Stockfish , Nc6 is considered to only be an inaccuracy.

And yet, according to opening principles it's a blunder. e4 Nc6 is also a big mistake, and Stockfish doesn't care since the loss is "only" 0.3 pawns.
