MOTS and bro ?

I got a query from ANL about Bro's capability to detect MOTS:

   "I had a question for you – I was at a talk last week, and someone was
   talking about a Man on the Side attack. The presenter had indicated that
   suricata was currently the only tool doing this detection, but that they
   thought an update to bro was in work – that would add that capability into
   bro as well.
   Was the speaker correct ?
   Do you know if bro currently can detect MOTS ?
   "

Wondering is MOTS detection this something we worry about in bro world and Any feedback for my reply ?
