shaded_face and shadow_over_eyes

There was an old thread (forum #15520) and it seems that [almost] everyone agreed on use of shaded_face. But there's also a shadow_over_eyes tag. Only the former has a wiki entry so I'm unsure...
Are there any differences between these two tags? And if there aren't, should one of the tags be abandoned in favor of another one?

BUMP: Uh, anyone?..

i would vote for an alias:
shadow over eyes -> shaded face

imo, the latter is shorter and fits better.

Well, I second this.

Did shadow over eyes -> shaded face
