That's a reasonable stance to take.  I don't think anything in the tree 
right now presents that problem.  I'll start sending out some patches 
and if you have specific concerns, we can talk about them 1-by-1.

Well with extboot in particular, the only interface is between the 
extboot option ROM and QEMU and I don't think that breaking that 
interface will matter much in practice.
