Most Linux dev environments do not need to be tied down to Intel. In fact it is more performant and efficient if you're working on ARM native on Linux. It was already a good Linux dev env before Rosetta 2 was on the scene, they just enabled more use cases with Rosetta 2.
I also do not see much need for Rosetta support for Linux as arm64 Linux works fine for most of my use cases. However it is definitely better to have Rosetta support than not having it.
This unfortunately only holds when working purely on open source. Shipped binaries for aarch64 are still not super common for proprietary things within the enterprise space.
