There's currently hullabaloo regarding the Global Privacy Control HTTP header as a spiritual successor to Do Not Track. It's already enforceable in California under the California Consumer Protection Act and the specification suggests they are also targeting GDPR compliance (although I don't know how close/feasible that is). If it were to see widespread adoption then all you would have to do is change a setting in your browser.
