Especially since it's difficult to do that accurately using a 
git-blame-style method. We can't use only count text that's persisted 
into the final version (in the style of WikiTrust's attribution), 
because if author A contributes a paragraph, and later editors 
completely rework the paragraph for wording, clarity, order, etc. to the 
extent that none of the original words remain verbatim, the final result 
may still be co-authored by A, both legally and morally speaking: you 
can do quite a bit of rewriting of a contribution while keeping the gist 
of it intact.
