I think we should consider disabling fallback altogether, there's no situation where it should be considered "correct" behavior and if triggered it would be hides a bug. Edit: thinking more on this, I realize I'm only considering the Windows scenario, but the fallback logic is identical all platforms. "Disabling" it for Windows would essentially be returning "NS_OK" on errors.
