but nobody is tracking anyone yet. The API is not yet in place, in fact there isn't even any idea on how that API should look like. This will likely take a few years to finalize (if ever).
Right now this is just one more field in a database (config file), nothing more and nothing less. Claiming it's the first step to "making sudo illegal" is quite a large stretch, don't you think? If that were the case, Windows DRM, Denuvo, and all those would also have been "the first step in making sudo illegal". Remember, circumventing DRM is against the law for ages now
