Having read the entire thread, I'm still not sure about the rationale. Sorry if I overlooked the answer.
If anything, the more specific using declaration (using std::foo) is worse than the using directive (using namespace std) as far as conflicts go. A using directive doesn't add a name to containing namespace, so you can always disambiguate later, unlike with using declaration, which can create unsolvable conflicts.
