I believe that digital fingerprinting is implicitly addressed in the standard, though not directly called our. Third parties that receive a DNT:1 signal may only collect data elements that are reasonably necessary for the enumerated permitted uses. That includes data elements that could be used to fingerprint a device. Some companies may believe that they need to use fingerprinting-type techniques for fraud and security purposes even for DNT:1 users (though they would have to justify that under the standard). But also keep in mind that much fingerprinting, as I understand it, is heavily dependent upon IP addresses, the use of which was envisioned for permitted uses even under the EFF/Moz/Stanford proposal.
However, if DNT is set at 0 or unset, the standard does not limit the use of fingerprinting, HTML5 cookies, drone surveillance, or anything else.
If I got any of this wrong, anyone, please feel free to correct me.
