I don'n really see the point of the question. I doubt you hope to find out there is a significant consumer-base in need, for reasons already mentioned, so are you asking if it's useless? I would say no, because making data accessible always is good. Personally, I don't care the slightest for stuff like football, hockey or whatever, but I remember struggling to find comprehensive data-set on human physical abilities, such as results in light&heavy athletics, which would include year, age, measurements and all other stuff that might be potentially interesting when analyzing something like that. Data on not-mainstream events is especially hard to find, which is a pity, as it is potentially even more interesting, because olympic athletes are obviously less human-like.
