As the Board have been rather slow with publicising the new privacy policy, I have taken the step of adding a notice to the bottom of [[MediaWiki:Copyrightstext]] on the English-language Wikipedia
I think including this information in the privacy policy and linking every project to that would make more sense that putting people off editing by having all this text on the actual edit page. Addressing whether we should be publicly displaying these IPs forever might be a better option than just trying to scare users into logging in. If the privacy policy is linked, please link to the official version on wikimediafoundation.org rather than to non-updated local copies.
