A lot of fulfilled requests are not posted as releases - perhaps because fulfilling a request is much easier than making a release, and does not create a future burden. But fulfilled request expire and disappear in a short time, so the releases are better for the site.
I believe that when the uploader chooses so, the burden of the release should go to the requester. I suggest adding a line to the "What to do after a request is fulfilled?" post ( viewtopic.php?f=72&t=19740 ):
If the person who fulfilled the request did not create a release, the requester should (or, "is encouraged to") create a release for the book themselves. See viewtopic.php?f=19&t=397
