Will the aforementioned goals enable direct boot using systemd-boot

If it supports multiboot2 with my extensions then it should work.
However, I do not think it is true because all is in development
state and nothing is set in stone. I am going to release next version
of my patches in November. I hope then we will be able to establish
main things and maybe it will be later sucked by systemd-boot. I think
that you should ask systemd-boot guys what they think about that.
fwiw, from #systemd IRC
Q: does/will systemd-boot work to boot Xen Dom0?
A: systemd-boot will boot anything that's an EFI program
Q: that's to mean, any EFI executable on the EFI partition?
A: yes. apparently that includes Xen itself, according to
https://wiki.archlinux.org/index.php/Xen#With_UEFI_support
"cp /usr/lib/efi/xen-4.4.0.efi /boot"
that's not the dom0 however, that's just the hypervisor
so the question is, how the hypervisor loads dom0
...
if you copy xen-x.y.z.efi as /boot/EFI/Boot/BOOTX64.EFI it'll be
booted by UEFI by default
you don't even need gummiboot/sd-boot
or you could `efibootmgr` it into your native UEFI boot menu
I never used xen, but it seems to read xen.cfg and load dom0 itself,
which is just fine
which, IIUC, is "probably should ... sort of".
I suspect wait and see is called for.
I'm hoping the Xen-on-UEFI work you're doing helps to smooth out the
boot process.
Thanks.
