I'm not totally against it, but the fact is that a lot of people milk the logging of IF at night.
350 Hrs of night and still no expert but I still haven't seen more than one or two times when there is no visual reference whatsoever (and yes, I fly in the middle of nowhere).
There is almost always a few stars or a ship or something, and even when you can't see anything then you should still be scanning outside for traffic so not truly flying 'solely' on the instruments like you are when in cloud.
If you're gonna log black hole night as IF and are visual the rest of the time then why do we even bother with a night column in the logbook? Because its not Day VMC, but IMHO its not IF either: Its night visual flying and its a whole skill of its own.
