Very true.
However the proximity of the wall behind the speakers could constrain the soundstage depth (assuming you can’t pull them out into the room as far with a long-wall setup). I’m not saying the one configuration is more right than the other, but ime there are tradeoffs which often require trying it both ways in order to evaluate reliably.
Imo the arguments for speakers with good radiation pattern control go well beyond minimizing sidewall reflections, but that is one of them.
You know, if your ears weren’t both on the left-hand side of your head, all this talk about soundstaging might make more sense...
Sorry, I couldn’t resist!!!
