So you would indeed possess a bit of self-awareness at the time of doing a RC, and that is good. But the purpose of the RC, I believe, isn't to create lucidity, but to confirm it. Yes, you can become aware that maybe you are dreaming when you see a dreamsign, but that bit of awareness might not be enough.
Without the physical reinforcement of a RC, that awareness will probably fade quickly, especially if you are in the midst of waking-life distractions. Or, worse, without a physical digression to doing a RC, when you see a dreamsign you will quickly learn to say to yourself, "Oh look, there's my dreamsign! But I know I'm in waking-life right now, so this is not a dream," followed by a return to whatever it was you were doing, dreamsign and the possibility of being in a dream forgotten. And, sure enough, this same thing will happen when you get that dreamsign in a NLD, without a hint of lucidity. Adding a RC to that moment of awareness sustains the moment, and confirms not only your state but your interest in that state. I think that is their real value, especially in the beginning of your lucid journey.
