The announcement doesn't actually say they are removing the Rosetta emulation. Rosetta 2 as a complete snapshot of macOS system frameworks is not the same thing as what is now called the virtualisation framework
Generally speaking of Rosetta means Rosetta 2 since Rosetta 1 is deprecated. It is very difficult to say what they are meaning.
The deprecation is mentioned in the context of Rosetta translation environment [1]. Rosetta for Linux uses same wording [2].
For example, Docker at least used to use this same binary translation internally year ago (the same tech as deprecation is mentioned). I don't know how it is today.
