I think Joey Hess' attempt at "solving the problem" deserves a mention.

It is open source (GPLV3) licensed. [not proprietary]

Written in Haskell. [cool aid]

Currently has 1200+ stars on Github and is part of at least Ubuntu (http://packages.ubuntu.com/search?keywords=git-annex) since 12.04. [shows something for support and adoption]

For the problem of large files I think Git LFS has largely won out over git annex, mostly because it's natively supported by GitHub and GitLab and requires no workflow changes to use.

Atlassian's Bitbucket and Microsoft's Visual Studio Team Services both also support Git LFS.

As of version 6 of git annex, the only thing an unlocked repo need other than the usual workflow is a `git annex sync`, that could be easily configured as a push hook.

There's a small but important trap to people who might want to use git-annex as a backup tool, namely that you can't store a git repo in git-annex.

Having nested git repositories is a solved problem both in git and in git-annex: use submodules.
