Currently, the editor's draft allows preventing content from being cached by
using the no-store http header. Often, developers cannot or do not know how to
modify http headers to block sensitive parts of a website from being cached
(when visited) by AppCache. e.g.:

A website containing both public and sensitive HTML pages needs to be made
available offline. The sensitive data must not be stored on the device. The
website is hosted on a virtual host and HTTP headers cannot be modified. The
web developer can prevent such pages from being cached by specifying them
directly in the manifest.
