The concern for code duplication is valid, but as the article mentioned it is also a while off until the Nova project is mainlined. I honestly never thought of how the work to bring in Rust to mainline may in effect lead to a more complete deprecation of older hardware as we start to change API’s older/unmaintained components aren’t updated. On the flip side, trimming out older stuff might save maintainer work going forward.

That and a rotating menu likely adds overhead costs as it prevents you from specializing (skills, equipment, and ingredients acquisition)
