My side question is what prevents arm64 from having the amd64 approach where AFAIUI the image is compressed but starts with a small stub that decompresses it.

This in turn broke grub-check- signatures, meaning that while cloud images booted in secure boot, you could not upgrade grub or install new kernels on secure systems as that would trigger a "you have unsigned kernels" message. grub 2.06 also fails to boot the images, as it verifies before decompressing. Work to fix grub to handle such images on arm64 for backward compatibility is tracked in bug 1954683. This bug is to reconsider whether the change is still necessary or could be removed in 22.04 such that we can have proper UEFI executables again.
