There is like 15 years of official guidance and case law on ePrivacy, with relevant guidance from the Art 29 Working Party (precursor to the current EDPB) published around 2014. But I don't think regulators are in a hurry to get into arguments about the finer points when the ePrivacy Regulation could be passed any year now, which would allow a more nuanced approach to cookies (e.g. allowing legitimate interest instead of consent).
