Then bringing up third party cookies seems like a red herring. They're worse, but for example I have a pi-hole at home. This prompt will probably mislead my wife into accepting it as an improvement, while it will presumably undermine the tracking mitigations I've set up for her until I go fix it.

This is unambiguously a privacy downgrade, regardless of what third party cookies may also be able to do.
