Well, it isn't entirely ahistorical to meddle in the affairs of others. I was thinking more of when you have an empire of 30 provinces, and then two small friends with each 3 provinces, it might be nice to avoid one of them destroying the other (for a variety of reasons, in my case simply because of a fondness of diversity).
I don't see it would "cheat" any more than one's current ability to negotiate an alliance. Mostly factions resist alliances unless its to their own advantages or if they are "persuaded". Nobody's saying it should be any different regarding meddling in alliances with other players. If you're Carthage, and Rome and Macedon and you are all at the same size, but Rome is defeating Macedon quickly, it would be realistic to have the option to attempt a peace to prevent Rome from swallowing Macedon and becoming twice your size (which would rather weaken your position)... But of course this isn't supposed to be particularly easy if Rome's war's goin' well... Prolly shouldn't be much easier than actually persuading a winning enemy AI to make peace (and that's completely impossible - without Force Diplomacy, but OF COURSE Force Diplomacy could cheat with the kind of option I'm suggesting, just as it already can with Become Protectorate)...
