When I had ranged SF, I was pretty sure that they consisted of really big guys throwing much smaller guys who would often die on impact.
Explain that in your scout reports!
("Sir, I see 50 big men accompanied by a horde of children. Clearly, the children won't be fighting, so we should only worry about the men." Poor guy never knew what hit him.)
More seriously, though, I was thinking of this myself. Even if we know whether or not SF are ranged, I know they sometimes have other abilities or oddities to them. Personally, I don't think this would hurt the role of SF.
