Right now we're in a phase where a lot of stuff (system-config-*, several parts of KDE and some other stuff) is getting ported from running the whole app under consolehelper or kdesu to PolicyKit mechanisms. This is generally seen as a *good* thing. It'd be really annoying to have to go through a FESCo vote for every single one of those. At the very least, I'd suggest adding the following clause to that paragraph: "Any mechanism which requires administrative authentication to perform the privileged action (e.g. auth_admin policy in PolicyKit, kdesu etc.) is NOT a privilege escalation mechanism for the purposes of this paragraph." Rationale: Such a policy does not impact the system's security as you have to enter the root password before doing anything dangerous, so none of the invariants under "Requirements" can be violated. And additionally, you can always as a user run the whole app under e.g. kdesu and thus "escalate your privileges" using the root password, so it doesn't make sense to police apps providing such a mechanism. What really matters for security is what you can do WITHOUT the root password. This is not really clear from the policy as written now, adding the suggested sentence would clarify it. (That said, I don't see even the clarified policy as being necessary. We have a set of guidelines, maintainers should follow them, why do we have to police them? As I explained before, there is no evidence that this is necessary or useful. The PackageKit issue was caused by lack of a policy, not lack of enforcement.)
