It's a good GNUism though, that I also wish the BSDs supported. No-one's saying that the BSDs should start supporting GNU style --long-options or switch to info instead of man, but friendlier help messages are always a nice thing.
Strictly speaking, those are usage messages not help messages.

That's not the dispute. It's a question of how much you value brevity.
