> There are, of course, many Docker repositories that lack ARM images, and you couldn’t use the exact same build locally as in production, but I think those are not actually huge, unresolvable issues. I'm not sure thats true. At the very least its going to suck for the first year as gaps are being filled, but those differences might matter too. I would hate to have to duplicate every single Dockerfile just because of this, as engineering orgs are typically heterogenous (win/lin/mac).

Should not need to duplicate the Dockerfiles; they should work as-is. The repositories may not contain aarch64 builds, but just like docker repos can contain windows container builds alongside linux, they can contain aarch64 alongside amd64, at the same URL, with the same tags, and in fact I think plenty of official images already have that. Few images should need Dockerfile changes unless they are bootstrapping from scratch. People are already using Docker and Kubernetes on Raspberry Pi and other small ARM devices.
