Prevent Google's FLoC by default
Google's new Federated Learning of Cohorts (FLOC) is criticized alot.
Many browser vendors don't want to support this new tracking technique and major softwares (like WordPress) plan to prevent this feature from being used on their sites by default.
Why doing this might be a good idea (especially in the case of a CMS) can be read in this WordPress proposal: https://make.wordpress.org/core/2021/04/18/proposal-treat-floc-as-a-security-concern/
Even though FLoC isn't tested in the EU yet, we may consider opting-out of it by default anyways. This can be done by sending the Permissions-Policy
response-header.
