I don't think it's helpful to be so nonchalant about Apple's breaking changes. It would come at significant cost to my organisation if Apple made changes to MacOS that meant Nix would no longer function. That almost happened. Luckily, the Nix developers found a workaround for Catalina, though it's awkward and it's more to maintain. Changing the arch is also costly and has far-reaching implications, and the work that goes into mitigating this is not insignificant. https://www.haskell.org/ghc/blog/20200515-ghc-on-arm.html https://www.haskell.org/ghc/blog/20200515-ghc-on-arm.html
