The justification thing is pretty much people misreading. Like I said, Alabanza has put every single domain on it's own IP forever. Their justification could be "That's how our panel works."
Here it is from ARIN:
The bold part is important and "technical" justification isn't the same as "you can't have these unless you prove you need them."
Kinda like saying, "Help yourself -- mind if we ask what you'll do with them?"
So, if you want the warm feeling of justifying it, you can just say something like, "All hosting accounts are offered as ecommerce-ready." There you go... can't have SSL without the IPs. Or build a panel that won't work otherwise, etc...
