The evolution from this seems to be to overload just one side of the pitch (or effectively just a quarter of it, instead of the entire opposition half) while leaving a wide attacker on the other side for a quick switch of play. The defending team is then forced into either committing more defenders into the overloaded side (and leaving 0 or 1 defenders to cover the lone winger) or staying symmetrical and thus likely not impeding the buildup enough. This is basically how Italy played in the Euros, overloading the left and leaving Chiesa open on the right thus creating valuable opportunities for him to take on a defender 1:1 with lots of space behind them. This is probably the best you can do if you want to have high possession without constantly running into brick walls.
