Surely homebrew will just extend to support building for ARM. For some packages that will “just work”, others will require some upgrades, but that’s already the case for OS upgrades now. Homebrew operate build servers to keep cached builds, I’m sure they can do the same for both ARM and x86. It would be a big job, but much of the software on Homebrew is already ARM compatible, and I think there’s a clear path to supporting that, which should make the migration relatively seamless for most developers I’d imagine. It won’t be without issue, but I don’t think it will hurt macOS as a development OS much in the long run.
