The point was to have something unique A codename would be unique.
Naming it Snapdragon-Devkit (or just devkit) will be confusing since
there was already a 2023 devkit (from Microsoft) with the Snapdragon
8cx Gen 3, and probably the next compute platform will also have a devkit
as well. So probably "X Elite devkit" could be the right option..
