For some of us, it's a lot more essential than just 'nice to have', Fixx. Me, for example, I do artwork for various record companies. It used to be, several years ago, that you could simply send the high-res PDF's of the finished artwork to your contact at the record company who, in turn, would forward it to the printer — a very fast and carefree workflow (though not without risk) — but in recent times, most major record companies have implemented rather complex and strenuous uploading software, synced and linked to their databases, that insists on several things to be part of the upload, one of them being the open files (for archiving purposes). Without those packaged open files (incl. images and fonts), an upload will simply be refused.
Only to say: for certain types of jobs that some of us are paid to do, packaging *is* very much a mission-critical feature.
There are work-arounds of course, but if you have to upload asap (and 'asap' is the most often used acronym in the music business) artwork that includes, say, a 36-page fully illustrated booklet, you don't really want to spend your precious time carefully rounding up any number of images and fonts from various folders on your HD's, all the time knowing that if you overlook just one single item, your upload will be mercilessly refused and you've wasted time of which you have none to spare.
I obviously speak from a personal and perhaps uncommon situation, but nothing would please me more than to see a 'Package-' or similarly named command added to the File-menu of Publisher, and have this command initiate a 100% accurate and reliable process.
(Sensationally brilliant software, by the way.)
