I mean, from what I can tell from quickly skimming the pull request, what it does is that when you save, it downloads whatever is currently on the remote, merges it with your local database and then uploads again (in hopes that the file on the server did not get modified in the meantime).

If your script does all that, I mean, congrats, but also it's still useful that no such script is needed anymore. Well, and that it happens automatically on save...
