It’s not all that expensive. The cost of storage is constantly decreasing over time. You can get a safe deposit box for something like $10/year if you also want the added benefit of an offline copy. I haven’t looked at cloud storage pricing, so I dunno what that runs.
Even with that repo it doesn’t come up. Not sure how long it takes for it to appear, GitHub is showing the release was tagged about three hours ago as of this writing.
