I guess you are referring to using stage0-uefi and live-bootstrap here,
right? Or maybe there's also some Guix work on top of it that wasn't
described in the blog yet. I haven't followed the development that
closely or maybe I have missed some announcement.

Yeah, I would argue so. Although depending on the requirements for the
bootstrap process the "diverse" part might get tricky.
