Anything you put in the host is potential attack surface. Plus, you're
not doing a different thing than anyone else and as you've found out it
may be easy for block device but not for everything else.
Every platform that QEMU supports is just using a firmware to do
firmware things; it can be U-Boot, EDK-2, SLOF, SeaBIOS, qboot, with
varying level of complexity. Some are doing -kernel in QEMU rather than
firmware, but that's where things end.
