There's another problem: You can only make machines so small. That also comes into play. Part of why bioware exists is to get around the limits of the mechanical.
Actually, the cyber olfactory booster is much more refined when it comes to picking up scents. Also the Olfactory Booster can pick up the emotional state of a person by scent. Page 331 of the BBB says the following:

This opens a completely new world of sensual information for the user, because smell carries much more information than a normal metahuman nose would ever be able to pick up—for example, many diseases can be identified by smell, and a metahuman body unconsciously produces odors corresponding to emotions (joy, fear, anger, etc.).
So since the Olfactory Booster can pick up exactly the same things that the Bioware version can, and can be over twice as sensitive as either the Bioware or the Metagenic versions... why doesn't it give bonuses to Social Tests?

The Vomeronasal Organ seems to combine the benefits of enhanced pheromone receptors and an olfactory booster. Similarly, the Biosonar quality gives you the benefits of having echolocation, vocal range enhancement, and hearing enhancement bioware.
Vomeronasal organ doesn't allow you to ID chemicals in the air. It gives you the enhanced pheromone receptors bioware for no Essence.

The description for enhanced pheromone receptors gives a pretty good rundown of the difference between it and olfactory boosters. Note that there is nothing stopping you from getting both modifications. In fact, the ability to shut down your sense of smell can be a benefit, since strong odors can make enhanced pheromone receptors actually penalize you.
In the description of the Booster it does allow the IDing of emotional states (as I quoted above). It doesn't say that you can ID someone by scent, but since you can ID diseases, I would think that it just an oversight by the writers about not being able to ID people by scent.
