So I decided to check this out. Used dd if=/dev/random to create a 100mb file, checked that in, used dd again to modify 10mb of that file, checked that in and the result were two 98mb objects.

Tracking changes of binaries makes a lot of sense if you use that to only store incremental changes to the file. Git stores each modification of a binary file as a separate blob since it doesn't know how to track its changes.

This is mitigated in large parts by the compression applied in git-gc, after packed, objects went from 196mb to 108mb.

Git LFS has the advantage of not pulling all versions of a large file, too. Instead, it only pulls the version it's checking out.

In our project it helped dramatically as you only pull X MB instead of X * Y MB when a CI or developer clone the (already big) repo.

This is true. Git-LFS can dramatically increase the size of the repository on-disk (e.g. in our GitLab cluster), but dramatically decrease the size of the clone a user must perform to get to work.

Note that this can now be accomplished with Git directly, by using --filter=blob:none when you clone; this will cause Git to basically lazy-load blobs (i.e. file contents) by only downloading blobs from the server when necessary (i.e. when checkout out, when doing a diff, etc).

I prefer keeping large files out of source control and thus far I've not encountered a problem where their introduction has been required.

While I share the sentiment of keeping large files out of source control, one use-case I believe warrants having large files in source control is game development.

that's about the only conceivable niche I can think of, even then I'm skeptical about turning the VCS into an asset manager

You can't diff and I'm not not convinced the VCS should carry the burden of version controlling assets. Seems better to have a separate dedicated system for such purposes

Then again I don't do game development so I'm not familiar with the requirements of such projects
