The only time the VERPed address comes into play is if there is a bounce generated to the envelope sender address that is created by Mailman, and even then it's just a matter of having the MTA pass everything it gets to mailman.

Almost. The delivery MTA in question has to recognise that

list-bounces+claw=kanga.nu@kanga.nu

is really the same as:

list-bounces@kanga.nu

and hand off appropriately. To do this the target MTA requires plus addressing support. Heck, that generic ability to distinguish and do that mapping is the definition of "plus addressing support in an MTA".
