If you're trusted but they're scumbags, the alliance doesn't become the sought-after Trusted Alliance, but a mere alliance of convenience like every other (ie, they'll help you if they get the chance, but they might just attack you if the odds are on their side and you're not both at war against a common enemy)
Yeah, that's the difference (I think) between leaked and official v1.2.; it didn't matter in leaked what their reputation was.
