Bring back P3P, with GDPR acting as the enforcement part (which was quite lacking when P3P was first proposed)? Might work quite nicely, and the support is in browsers already, it just tends to be ignored.
I've thought exactly the same and I think now might exactly be the right time to bring it back. However can the client tell to the server if it consents or not? Second problem is of course that malicious or lazy site admins won't use P3P just that they can annoy users to click Accept.
