Markdown Annotations are certainly interesting and I understand where the hash idea came from, but this requirement adds friction to hand authorship, and requires new custom parsing logic for markdown renderers.

I would argue it should instead be:

- file.md

- .file.md.owners

Where the owners file is generated / readable by a program supporting this behavior, along with a reference to the original file and its hash.

This provides the same information and capabilities, while decoupling it from the source. It also means you can retroactively generate ownership without modifying original work.
