Well, it has an unusual spectral response, which differentiates it a little bit from being "just another slow film". And if I'm not mistaken it's slower than anything currently available apart from ortho films and microfilm-based exotica.

I'm not sure that long exposures are its forte especially (unless the point is "slowest film possible in order to make the exposure long"---but you could do that with a neutral density filter too), although as far as I remember it has good-looking reciprocity data. I think it would be a good film for your "kill the background" idea or for light painting, though.
