Such steps will certainly impact neural development for the better, although it is likely beyond our capacity to accurately measure how much.
One additional point about the dynamism of human nature is important to note.

Epigenetic forces, however, are more amenable to change.
It is possible to reduce the amount of stress on pregnant mothers caused by poverty or to remove young children from a war zone, where their developing brains are subject to extreme anxiety.
