They're valuable for when you're looking for why they broke the code base. This looks like dead code, will I break anything if I remove it? Git blame gets me the ticket number, details on the particular change being made, and (if the author writes their commits well) related files and tests associated with this change. From there, I can see if the other code has since been removed, or if there's an edge case I didn't think of, or if the thing was never plugged in in the first place, or if this is a bug no one has noticed. All within two minutes, and without needing to ask the author (if they're even still available).
