It does seem like it would be useful for the TAG finding to explicitly address this point.

To summarize, sites are still exposing information about their users when they force visitors to use HTTP, even if there are no authentication cookies. In particular, the user’s reading habits are exposed (which page on your site are they reading? does that page contain words of political interest?). Non-authentication cookies are used to surveil users or identify them for more invasive attack [0].

Also, without integrity guarantees, HTTP sites expose their users to the risk of running any script the attacker wishes to introduce, including potentially asking for access to sensitive device APIs. Network attackers can also introduce identifiers or modify content for HTTP browsing. That is, integrity also helps with confidentiality and other privacy concerns [1].
