Fraunces is a beautiful variable serif https://github.com/undercasetype/Fraunces

Though not specified in the repo, author's website states "Commissioned by: Google Fonts", so I'm closing the issue as redundant.

Not yet, but it's still in beta https://github.com/undercasetype/Fraunces/releases
I'm guessing it will be added as soon as it has a finished version.
