I can see valuing some clearly passion driven extracurricular activity. Like if someone is a top SO contributor, that's cool. Or if they're part of a big open source project. Or also if they volunteer at a soup kitchen or charity. Stuff like that may be worth including on your cv to show what your interests are. I wouldn't weight it much differently than anything on the hobbies section, but it's still cool.
Personally I'd be wary of hiring someone who had done just the right amount of all this stuff, and who appeared to be soulessly gaming metrics instead of actually being interested in stuff. Otoh, there are jobs and work environments that fit well for that kind of person, and screenings that optimize to make sure that's what they get. It's just as important for people that aren't that way to not get accidentally stuck in such an environment. Like a "17 pieces of flare is only the minimum" kind of vibe
