Minor nit.

For this to be a baseline, you would need to have another algorithm before "before", i.e., without any of these notes implementation.

Comparison with "before" alone is not meaningful. That is like starting with a state with unknown performance regression compared to the stock version, and then boast improvements made by various variations.

You would need to compare overhead of various "algorithms" with the stock git in "no-notes" case as well. It would give us the true performance cost of supporting notes.
