Opt out of Google's FLoC

Google is starting to track site visitors even if such a site has zero relationships with Google Analytics. Though it is currently said that it's being tested on only a handful of Google Chrome users, we should prepare and treat this as a security concern.

Recently, Plausible Analytics has opted out and there is a proposal to do the same for WordPress.

Now, how to do this is pretty simple. We just set the following header: Permissions-Policy: interest-cohort=()

I'd imagine we just add setting that header to the webserver templates. Either that, or there's some clever way to set these headers from Pleroma. Who knows? IDK.
