amazon-import - improvement about packer-plugin-amazon HOT 1 OPEN

I'm attempting to build a slew of slightly different Amazon Linux images locally with qemu, and then trying to import them with amazon-import, and similar to what's mentioned here, it's complaining with...

==> Some builds didn't complete successfully and had errors:
--> alpine.qemu.edge-aarch64-uefi-tiny-aws: 1 error(s) occurred:

* Post-processor failed: Import task import-ami-01c8ff48cc465f998 failed with status message: ClientError: Unsupported kernel version virt, error: ResourceNotReady: failed waiting for successful resource state
--> alpine.qemu.edge-x86_64-bios-tiny-aws: 1 error(s) occurred:

* Post-processor failed: Import task import-ami-0116dd9338d501277 failed with status message: ClientError: Unknown OS / Missing OS files., error: ResourceNotReady: failed waiting for successful resource state

==> Builds finished but no artifacts were created.

The local disk images are raw format. Difference between the first and second builds above is that aarch64 partitions the disk (GPT/FAT32 for EFI, ext4 for root, using GRUB EFI), and x86_64 formats the whole disk as ext4 instead of partitioning, and uses extlinux as the bootloader.

I've yet to try the above s3 -> import-snapshot -> register-ami process manually, but having this officially supported by a Packer post processor would be very handy...
