@maralorn if you have time to take a look that would be appreciated 🙏 I wasn't sure if this strictly needed to go to haskell-updates beforehand, but selfishly since I'd like hydra to build and cache aarch64-darwin I thought I'd submit against master.

I guess we should add a loud comment into the release-haskell.nix file, that this place needs to be kept in sync.
