Should we use git-lfs to handle the media files?

[Artoria2e5]

When adding the 2015 submodule, git took a long time unpacking the objects, and the big fat media files are definitely ones to blame.

Can we use git-lfs to handle this? I think GitHub provides some free 1GB storage...

That 1GB is real... But what if we will fill that up eventually?

Sure we can...

However I wonder if git-lfs can use a third-party link so that we can host the files on our mirror site.
