The new behavior forces it to be stated explicitly. The rule is that explicitly specified options have priority over the implicitly added ones from options enabling several suboptions. So, when you have -Wformat-security -Wno-format, the latter doesn't disable -Wformat-security, because it has been explicit. This is how the option handling always behaved. The bug fix I've done (based on a bugreport in Fedora bugzilla) is that -Werror=<whatever> is considered explicit -W<whatever>.
