I agree that shomen-uchi nikyo is practically not useful, but often what we are learning is to move from one technique or body position to another. Thus it is useful to learn how to do nikkyo from a position in which your hand is already grabbing the wrist (ikkyo style). Also, talking about utility can be a bit self-delusional, suggesting that what we do in the dojo is realistic rather than just training.
I'm pretty much with Ian on this.
If you take aikido moves as techiques with the aim being to reproduce that technique then shomenuchi nikkyo usefulness is questionable (although one of my students claims to have used nikkyo very effectively during security work).
If you look at it as a tool to learn other things then it can be highly effective in teaching Aikido bases.
