Very rarely, beyond a couple weeks of commits. In those cases it is more a question of "did some particular commit hit branch XYZ?". I wouldn't call that source-control-arachaeology. I'm at the stage where if someone suggests that we try to keep a linear history in git I push back and argue that it isn't worth the extra effort compared to the gains.
