> that's not running a 64bit userspace on a 32bit kernel,
Why not? You have a 64bit system on top, a 32bit kernel at the bottom
and whether execution of those 64bit binaries is performed directly by
the CPU or via binfmt + qemu is just an implementation detail.
There is an important difference, of course: while you can run a "pure
i386" system on top of an amd64 kernel, you'll need some of the 32bit
system installed (e.g. qemu) in order to run the rest of the system.

It's typically used to run systems from an "incomparable" CPU.
E.g. to run RISC-V code on an PC. Which one is older and which one is
newer doesn't really matter.
