Back when the Apache OpenOffice project was still alive, the LibreOffice project used git notes to track, for each commit to Apache OpenOffice, whether it was ignored (usually for being specific to the obsolete openoffice.org build system), redundant with a libreoffice commit (usually because the LibreOffice project had already fixed the same issue in a better way several years before), or cherry-picked into the libreoffice tree (this was the rarest case; in these last two cases, it also pointed to the relevant libreoffice commit); an aoo commit without git notes meant it had not been looked at yet. While the LibreOffice project stopped doing that a couple of years ago (probably because there was no longer anything interesting happening in the aoo repository), you can still see the branch they used to mirror the Apache OpenOffice tree, still with the git notes, at https://git.libreoffice.org/core/+/refs/heads/aoo/trunk https://git.libreoffice.org/core/+/refs/heads/aoo/trunk (follow the parent links to see more, or clone the repository locally and look at that branch with gitk, which also shows the git notes).
