This works just fine with IMP 5.  Responding, e.g., to a message from  
foo+bar at example.com correctly sets the To: address on the compose  
message to foo+bar at example.com.

To the extent this doesn't already work, no.  Why would you need this  
anyway?  Such e-mail tags are meant to be transparent to everyone  
outside of the local MTA anyway.
