Dangerous Sixth File

This was taken from a recent game.  It should be instructive to the beginner especially, and perhaps to the absent-minded expert as well.

There are two diagonals which should be protected especially at the opening: the e1-h4 for White and e8-h5 for Black.  Pushing the f pawn prematurely opens this diagonal, putting the king in peril.  Lesson: don't push those pawns!  This also focuses the problem of many players who are pawn-pushers, as if there are only pawns on the board.  Pawn formation should be in one's mind in the opening too.

Any evidence of this?  See the diagram.
