To be reliable you'd need to support disassembling the binaries 
installed and working out what the arguments are meant to look like. 
This doesn't seem like a great way to spend time. Remember that the 
incompatibility isn't between libguestfs and the guest, it's between the 
host grub and the guest grub. Both of those can change without 
libguestfs's knowledge.
