Sevenstrokeroll, no, I taxiied rapidly to the gate and had the passengers deplane so fire personnel could check the cabin. I did set up for an autoland in case things deteriorated. An oven which was on the aux electrical bus which I immediately turned off was the source. After my incident it was changed from a checklist item to a memory item. If things had deteriorated we would have done an autoland and evacuated on the runway if necessary.
Interesting info on the captain not commanding the evacuation. My wife is a FA at AA so I know they can initiate an evacuation on their own if deemed necessary in an emergency. What if the captain had decided to taxi clear of the runway? As you said, there must be more to this event.
