It seems from the current list of students that the department isn't in the practice of reaching out in the case of finalists deciding not to attend/who are rejected at a later date. As you can note, there are students in different stages of the program; some years saw no admissions at all whereas others had two admits.
What I think is that they likely extend their finalist offers and decisions are final irrespective of yield.
I've been contacted by French faculty as well, which makes me wonder whether or not the plurality vote has to be obtained from all French AND Italian faculty, or just your core concentration faculty members.
