... I think all dxvk developers have local clones of the repository (git is distributed in its very nature anyway), so even if let's say disaster would strike and GitHub would suddenly vanish off the face of the world, it wouldn't be that big of a problem. Anyway, just my 2 cents.
There's even an ancient version of DXVK in GitHubs arctic vault, so even if civilization ended, we could still render D3D11 games on Linux. :)
Not interested.
