I want to completely agree with this. I've had the experience of asking for source *when the final published paper said it would be available* and still had them refuse on the grounds that it "wasn't ready yet". Two years after publication.
As for the correspondence section, in many computer related fields people publish in conferences. Good luck getting anything out of a conference after it is finished. I've found papers that have had actively inaccurate information, but there's no one to complain to, no mechanism for getting a correction published, and the original authors don't care because hey they got another publication.
