Boot camp is a windows problem. This can be done today on apple silicon but Microsoft dosent want to go through the effort to support it.
Arm-based windows support via Parallels does work, but AFAICT there's no official way to buy a Windows license due to a Microsoft/Qualcomm partnership.
I think WoA used to be exclusive to Qualcomm, but that hasn’t been true for at least a couple years, maybe longer.
Microsoft is pretty justified not wanting to support that, versus UEFI on OG Bootcamp. The majority of Linux distros don't ship image support for iBoot either.
Did Apple ever support UEFI? I thought it was only ever EFI; no U.
In any case, EFI is still well-supported by OS installers. iBoot is not.
