Git-backed Settings Sync to allow sharing of settings with others

[macintacos]

One of the advantages that I really liked when using the other Settings Sync extension is that you can put your settings in a public gist and share it with others. In the spirit of dotfiles, I find inspiration by looking at other folk's configurations. I'd argue that adding the ability to sync your settings in a "public" location (that only the user can control) would be a net-benefit for the editor and its community as a whole.

With the new syncing implementation that's built into VSCode, it seems like sharing your settings in a repository for others to look at is not possible. Can this please be added to VSCode's implementation; at least as an option? Is this already on the roadmap somewhere that I've been unable to find? If that's not something that will get added, I think I'm only going to be using this syncing functionality as a "backup" instead of my primary method of syncing.
