> Browsing annotations and reading commit messages is not "detective work", it's absolutely straightforward and means you're actually using your VCS as something more than a glorified tarballs directory. That works until the VCS history is lost. For an on-topic example, this usually happens when a formerly closed-source code is released to the public: only the final state of the source code is released, with none of the VCS history. This can also happen when changing to another VCS; often the history is kept only on the former VCS. Some projects have gone through several of these events; I challenge you to find early StarOffice history when trying to understand why some piece of LibreOffice code is written that way. And there's also the tendency in some places to reference bug tracker issues in commit messages. Said bug trackers tend to have an even shorter life than the VCS. "Fixes issue #1234" is useless when issue 1234 was on the old bug tracker, and both it and the new bug tracker were lost when the company was acquired and migrated to a third bug tracker.
