So I updated to the current main branch, and it's now working (commit
782418a166).
So I rebased my changes on top of main and it noots now.

So it appears that it broke and came back to life. I could try and bisect it,
but it would take forever on my machine.

I get this warning, for whatever that's worth:
BdsDxe: loading Boot0001 "UEFI QEMU QEMU HARDDISK " from
PciRoot(0x0)/Pci(0x3,0x0)/Scsi(0x0,0x0)
BdsDxe: starting Boot0001 "UEFI QEMU QEMU HARDDISK " from
PciRoot(0x0)/Pci(0x3,0x0)/Scsi(0x0,0x0)
systemd-boot@0x7d14a000,0x7d16b000
systemd-stub@0x70189000,0x701a4000
Overlapping PE sections detected. Boot may fail due to image memory corruption!
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI stub: Measured initrd data into PCR 9

Thanks for the help and suggestions along the way,
