Comment(by nacin):

 I've spent a while going over the original changesets, MU code, and other
 documentation on this. Unless I am misreading this, an option cannot be
 whitelisted while being on an 'options' option_page, unless the option was
 manually whitelisted without being properly registered.

 There are technically other ways to "whitelist" options, such as via the
 filter, but MU 2.7+ only checks for {{{'options' == $option_page}}}.
 Donncha wrote register_setting() and also the MU 2.7+ whitelist
 enforcement check, so I used his narrow implementation when I wrote
 [13785].

 The $unregistered check was added to the same branch of code as the
 original MU check, but I realized that was preventing the hidden
 options.php form from functioning. So I've moved it to a better location
 in [13789].
