It seems to talk about Rosetta 2 as a whole, which is what the containerization framework depends on to support running amd64 binaries inside Linux VMs (even though the kernel still needs to be arm)

Is there a separate part of Rosetta that is implemented for the VM stuff? I was under the impression Rosetta was some kind of XPC service that would translate executable pages for Hypervisor Framework as they were faulted in, did I just misunderstand how the thing works under the hood? Are there two Rosettas?

I cannot tell you about implementation difference but what I mean is that this only talks about Rosetta 2 for Mac apps. Rosetta for Linux is a feature of the Virtualization framework that’s documented in a completely different place. And this message says a part of Rosetta for macOS will stick around, so I would be surprised if they removed the Linux part.

On the Linux side, Rosetta is an executable that you hook up with binfmt to run AMD64 binaries, like how you might use Wine for windows binaries

Rosetta Linux executable can be used without host hardware/software support; for example, you can run it on AWS's Graviton instances.

However, to get performance benefits, you still need to have hardware support, and have Rosetta installed on macOS [1].

TFA is quite vague about what is being deprecated.

The "other" part of Rosetta is having all system frameworks being also compiled for x86_64, and being supported running in this configuration.
