I am afraid making VERP for confirmation could brake the confirmation 
process because of many kind of automatic reply that could make unwanted 
validation. It is exactly why we use VERP for the welcome message : any 
automatic answer to the welcome message push the new subscriber out of 
the list. May be you could try to use In-Reply-To: based on message-id ? 
The first think to do is to collect many automatic answers and check if 
they contain this header. If not, tell us we will introduce this.
