Earlier this week there was a proposal submitted by Carike on WordPress.org to treat Google‘s cookie replacement — Federated Learning of Cohorts (FLoC) — as a “security concern” and add a method in WordPress core to block it. ⛔
Many people weighed in on the proposal in the comments, and even mainstream tech media (incorrectly) picked up and incorrectly stated WordPress core would be blocking FLoC.
From a technical standpoint, the process isn't difficult: at least one person (Hendrik Luehrsen) has already published a WordPress plugin to opt out of FLoC.
Helen Hou-Sandi has opened a Trac ticket to monitor and discuss the issue with the ticket “milestoned for 5.8 to ensure that it remains on the radar but if information and consensus evolve rapidly we can certainly come back to shaping a proposal around minor release inclusion.”
