Another little-known feature is git trailers:

These are key-value structures data that can be included on a commit when it is created. These are used by some systems for attaching metadata. For example, Gerrit uses this for attaching its Change-Id.

TIL the `--trailer` CLI option. I used to edit the commit message in a text editor and manually add the trailers (which works for GitHub `Co-Authored-By`).

being able to use them with `git log` format is pretty cool.

I’ve wanted to use them to keep track of whether a change was done by AI.

Lack of support was a big problem.
