that should only be the option of last resort. First it's harder to file steel 6mm of steel vs 3mm of aluminum, but more important is that filing the dropouts will effect how the wheel sits in the fork, and would need to be cone fairly precisely to avoid changing the tracking of the bike.
Usually I suggest filing the dropouts only to correct a defect whereby the wheel is not in plumb.
