Comment 2 for bug 1369128

PCRUD delete on "bre" was never added, because the existing API does more than delete the bib. It protects against deleting bibs w/ active call numbers, updates the MARC (leader/05), cancels holds, and queues hold notifications. I'm not against adding the PCRUD entry, because it might be useful in some context, but I'd prefer it be accompanied by a "use at own risk" warning in the IDL that basically says to use the API instead.
