I'm not sure I agree - in my case (which appears to be similar to the OPs, and is certainly a common usage pattern), the use of recipient verification between edge MXs and mailbox servers, both under my control, is quite OK using the null sender. All the processing (including special handling for bounces) that's going to get done is done on the MX; the verification step is only there to check for non-existant localparts. In fact, I suspect that use_sender would render this mechanism less efficient because of caching - once a single localpart has been discovered non-existant, I want it to stay that way for all senders. Happy to agree that other patterns do require use_sender, but it's not universal.
