I'd be OK with either of those. Or indeed with - adjusting the emulator so it always returns a non-OK value when it needs the caller to do something to make the state consistent; or - keeping the injection hook but moving it to the end of the emulation, as a sort of write-back of the emulator's internal event state to the guest. That would let the emulator DTRT about tracking events internally but still avoid any risk that the caller forgets to inject the event.
