For features that ship with ZCS, are missing official TechDocs (install, config, etc) considered a 'bug' or an 'enhancement' by @Zimbra?

Specifically, when WE file @bugzilla about the missing docs, what 'Severity' should be selected?

Here's one example -- missing cbpolicyd documentation (https://bugzilla.zimbra.com/show_bug.cgi?id=70376) -- that:

(1) was filed over a year ago (2012-02-21) as an 'enhancement' to v7.1.4
(2) hasn't been completed in/by 8.0.4
(3) can't get any attention/response from the "Assigned To"
(4) won't allow users to modigy "Version Found" or "Severity"
