Would be interesting to see it paired with the original smell system if that ever returns.
Personally I think it would rather have an opposite effect- Zombies would not be as easily able to recognize your location by scent if you're unclean, but Animals would.
Reason being, Zombies are hunting for the player based on their remnant knowledge and instincts of a modern world- Lights, fires, mining and other activities, etc. So, A 'Clean' smelling human, the scent of soap/perfumes and scents is going to attract them far more than an unga-bunga caveman who hasn't showered in three months. Indeed, a common trope in zombie stories is to do stuff like slathering yourself with zombie guts or mud or whatever to mask that scent of cleanliness.
For similar reasons, cooking more complex meals and adding spices and the like should attract zombies more than just grilling meat over a fire, and flowery scented plants like crysanthemum and goldenrod, aloe and the like should lure them as well- Especially when you've got them concentrated in a farming area as players tend to do.
Animals though, when you're emitting stenches that foul, they'll be able to track you for miles- While scents like flowers and general cleanliness would make it easier to go unnoticed.
IMO, of course.
