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.
Because it's a different thing than native execution, irrelevant in the context of the discussion, and fairly uninteresting to belabor the point that you can run basically anything in an emulator.
