Yes, VERP is the only way to be sure to recognize a bounce. Adding the 
list message sequence number in  the VERP could be a way to identify the 
message incriminated by the bounce. The requested feature could be 
activated only if VERP is activated for 100% of subscribers.

I imagine that the distribution status page for each message that list 
each receipient that didn't receive the message could be activated from 
archives web page. The list owner or message sender may access to this 
page according to their privilege : (at least review privilege is 
required in order to access this page because this page show some of the 
list subscribers). If an alarm is needed, it may not be a good idea to 
send a notice to the message sender for each bounce message received : 
it may be too much. Most of the bounce occurs a few minutes after the 
message was sent, later bounces arrive 3 days later so a notification 
could be sent in that timetable.
