Another way could be to use add romfile option to netX in vmid.conf,
and update it at vm_start if a new rom version is available (use glob on rom directory, take rom with biggest number suffix)

It's possible also to use qmp "info qtree", to retrieve current rom filenames, 
on source vm. 
(we could keep roms with version suffix for examples)

I doubt we can fix this cleanly - what if we need to update the bios file again 
because of a bug? Wait every time for the next major release?
