This whole disavow tool is designed to turn us into unpaid manual reviewers for Google, and the data they collect from this will likely be used for another purpose in the future.
I don't think it's designed to do this but it is another data set that will undoubtedly be tested against and if the search results end up better then of course they'll test employing it to a limited degree.
The only problem I see with this is sites that abuse the system, or don't know what they are doing, marking trusted sites as spam via disavow. Still, I don't think many webmasters will disavow good links from their own sites, so maybe...
People said the same things about DMCA requests.
