+					<h5>Editorial Note on User Privacy</h3>
+					<p>Due to community feedback related to privacy, this feature may be marked as at-risk or removed. The working group acknowledges its usefulness in complex web applications such as enterprise document-editing suites, but also acknowledges the fact that its utility may be easily misunderstood or potentially misused.</p>
+					<p>For example, the typing echo or other verbosity settings would be useful today, for sites such as Google Docs and iWork for iCloud. These applications use custom display views that are not able to be made accessible through conventional means, so speech output is controlled via live region announcements. The web application does not otherwise have access to user settings such as typing echo, so without access to this feature, the web application could not mimic the user's preferred output.</p>
+					<p>One potential misuse is for user metric or tracking. Even with the <a href="">best of intentions</a>, this is a potentially harmful misuse of the API. There are currently very strict user <a href="#privacy-model">privacy model</a> requirements to implement this feature in a reasonably safe and secure way, but if the working group is not comfortable in the implementation's ability to sufficiently prevent this type of misuse, we will remove the feature.</p>
