Sure, how would you like to get in touch? You have a discord, right? I actually was looking at your project and was thinking of opening a simple PR. (same username)

I have some more examples git-annex repos:

This is an annex repo I made of this popular abandonware website:

https://github.com/unqueued/repo.macintoshgarden.org-fileset

And some podcasts

https://github.com/unqueued/radiolab-fileset

https://github.com/unqueued/ratholeradio-archive

What's cool is that people can use standard pull requests to add files to the repo. And the repo itself is small, but it can represent huge filesets. Datalad has some really fascinating medical imaging data repos that are massive (https://www.datalad.org/datasets.html).

If you wanna see a really good example of a repo with versioned binary files, check this out the git annex repo of previous git-annex binary releases:

https://downloads.kitenet.net/.git/

You can just use standard git workflows to see previous revisions of a file (well, previous hashes) but it is really easy to hook into.
