Question: prune lfs files

[memeplex]

Sorry for asking here but I didn't found a better place.

I would like to prune old versions from local lfs storage, in a similar way as git lfs prune does. The problem with git lfs prune is that it's intended to free local space but doesn't actually change history, so the reference to the old version remains. If I then want to clone or push the repo I get errors like

Your push referenced at least 1 unknown Git LFS object

So I would like to remove those old versions altogether. I could be something like "keep just the newest k versions" or "remove all versions older than t" or "remove all versions that are larger than s". In all cases, the last version should be kept and when a version is deleted both the file and the reference should be removed.

Thanks!
