Looks like this was first started back in 2023.
Lots of folks use Raspberry Pi's and BeagleBoards/BeagleBones (and other platforms) to run Linux on ARM64 to do automated testing, prototyping etc.. Therefore I would think there would be more of a use case to have CSC run on ARM64 than Windows but I guess I'm wrong. It would be extremely helpful for us though.
