This is an interesting thread with no right answer.
Again, what can the FA say that might cause me to go around, assuming 3 green and everything looking good? "We're on fire." Well, we are landing in moments anyhow.
Then, I got to thinking a bit more, and the danger isn't from some dude with his pants around his ankles at touchdown, it is someone walking the aisle, trying to get back to his seat during the flare or TD. The potential for him to fall and injure someone or himself is not small.
Worst case: There's a cart loose. A cart cannot grab on to a seat back. So I'm starting to change my mind... IF the phone is answered, there just may be some info that might cause a go-around.
