Yeah it doesn't! You can play the Berlin where black accept the inferior position to fight for or the Jaenish where black has 15 moves to gain something either wise is positionally lost! Come on...what are we talking now!?
Bullshit' of course. The main idea of the Jaenisch currently is a pawn down ending where Black has fair and easy compensation.
It's not the same with a Marshall attack where white can play a anti-Marshall if this is what your meaning is about. Here black does not have any kind of Queen side expansion and white didn't avoid d4. The same Kasparov used to play always Anti-Marshall because of the drawish positions black can force but that proves a lot of the power of Bb5. Today the 8.a4 anti-Marshall line consider's one of the most interesting lines cause of that Queen side expansion.
