Okay. So answer me, truthfully, just between you and me and some of our closest friends... :)
If I were to present to you a piece of paper with the hyphen/minus, true hyphen, non-breaking hyphen, and true minus printed out, could you distinguish them from each other? Other than the difference between breaking and non-breaking I don't really see the point. Or is it about the computer being able to tell the difference for search-and-replace, etc.?
Minus traditionally looks very different than hyphen (and its substantially longer, more like an en dash), but that all depends on the font used for display, of course. And, yes, U+2010 was AFAIK added to Unicode so that you can unambiguously state whether something is a hyphen or a minus.
