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.
