I see cigar leaf for what it is at face value. It is a color cured, fermented burley, sure and simple. It is an ingredient that can be used in anything. Saying that they are strictly for cigars is like saying that Red Virginias are strictly for cigarettes, because it is a leaf that is processed for cigarettes which has sort of crossed over. Or, like saying that peppers are strictly for chili.
It is a leaf that can be blend to make new things, and I always tell people who ask about cigar leaf blends that if you expect a cigar, buy a cigar, but if you want something completely different give a cigar leaf blend a try. Because there is no way to get a cigar effect from the pipe. But, if it does add texture, deeper rich flavors, and strength to blends, with subtle nuances of flavors that can be played with by blenders.
Now Gurkha Ninjas... if you like a strong robust dark leaf, this one will sneak up on you, ha ha. My only complaint is that they are too small. Just went I am settling into my chair, it's gone. I keep a few in the humidor at all times. I highly recommend them.
