Cosmopolitan is cool and I have some uses in mind for it that I wish to get to.

But what I don't understand is the use case for an exe which supports both running as an user app on normal operating systems and from the BIOS. For which application specifically does it makes sense to run it in both these very different contexts?

Look at it the other way round, from someone who wants to put something in the BIOS. It's going to be much more convenient to be able to test as much of that as possible without leaving user mode and actually having to run it by restarting a (potentially virtual) machine.

But also: sbcl. You just know someone's going to do lisp-from-boot with this, if they haven't already.

Emacs could become an actual operating system!
