I'm sorry - but all that this discussion seems to be about, is that PaxTeam (and others) would like to developers to write in changelogs, if they know the bug fixed, to have a security impact. That's all.
Currently, they - by their own admission - choose not to reveal such knowledge in changelogs (which could defintely be called a "lie of omission").
I don't think anyone disagrees with the fact, that even if such knowledge was in the changelog, many bugfixes, would not be known by the dev(s) to be security fixes as well - and as such, one will never be able to simple grep for a "Security fix" or similar in changelogs to know when to upgrade to stay secure - such is the world of computers today :)
