Narrative:

Air carrier X taxied out for departure runway 1R sfo 8 departure. On departure, 1 mi, air carrier X advised local control they needed to return for landing. Local control worked them in right traffic runway 28R. Traffic was sent around and/or moved to runway 28L to accommodate. Air carrier X was asked if declaring an emergency or needed assistance. 'No,' they replied. After landing it was discovered smoke in the cabin was the reason for returning. All of us in the tower would have felt more comfortable knowing this, and having declared the emergency ourselves. The aircraft taxied to the ramp.
