This makes it much harder to cross-compile QEMU.  Also, I wonder how 
hard it would be to apply the same approach to the main QEMU binary 
which already uses QemuOpts for its more complex arguments; for sure you 
risk that accumulating multiple layers of abstractions makes the code 
even harder to read than it is now.
