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.
