Interesting effect of GDPR and DNT (do-not-track) header

I was thinking a bit about those two, it produces an interesting effect, by having it turned on, you are telling the site that you don't want to be tracked. Before GDPR came to effect, industry completely ignored it but the question remains what this means under GDPR. You are clearly stating upfront that you don't want to be tracked to the sites which are required to ask you about handling of your personal data and the purpose of it (which is largely tracking). Showing you the dialogs to get opt in can be easly considered as deliberate annoying users which have already tell you "do not track". This might have interesting implications for pretty much dead DNT and might make comeback in full scale backed up with GDPR legislation. Certanly something to ask EC office of Data Protection Officer.
