There’s some more context in a proposal from the folks behind this project to upstream the needed Go runtime hooks into Go proper.

From what I can tell, the core Go team seems generally favorable to it, so seems like a decent chance it will happen.

From:

#73608 proposal: all: add bare metal support

https://github.com/golang/go/issues/73608

> Go applications built with GOOS=none would run on bare metal, without any underlying OS. All required support is provided by the Go runtime and external driver packages, also written in Go.

And:

> These hooks act as a "Rosetta Stone" for integration of a freestanding Go runtime within an arbitrary environment, whether bare metal or OS supported.
