Treating every listening note as a final review leaves little room for change. A listening archive can instead preserve the question I had at a particular time. A later note can add a new relationship beside it without erasing the earlier one.
In a Git-backed blog, content files and their change history live in the same system. You can trace when a sentence changed, when metadata moved, and which edits can be reverted. But Git alone does not provide the entire publishing experience.
A piece can be about an old period and still be written today. An old note can also be published for the first time today. Forcing those events into one date changes the meaning of the archive.
