I've sent a mail to support@github.com (salutations removed):
Will "git --follow" functionality ever be implemented on Github? If yes, where can I track its progress?
(By "git --follow", I mean a way to easily see the object revisions before a rename. Currently, when an item is renamed, Github doesn't offer an easy way to display the directory / file history.)

This is something a few other users have requested as well -- we might add it in the future. We currently don't have a public issue tracker, but I'll put another +1 next to it on the Feature Request List™ for the team to see.
So, "git --follow" is unfortunately not supported yet.
To get such functionality in the meantime, I guess you could write a user script that looks up the hash of the parent object, (recursively) look up its history and render the result.
