The idea is having rooms have their own smell message, which could provide extra flavor text as well as info about what's happened in the room. Back when I first learned about the smell command, I thought this was actually how it worked.
This could be tied in with forensics, having places where there's fires or explosions having a lingering scent of smoke. Maybe a forensics device could analyze the scent, and figure out exactly what it came from, and when it happened. It could also be something that players change change for apartments when redecorating.
