I think if anything we should have no default at all.  But if I had my way:

1) if=none would be deprecated (but with a much longer cycle than 1 
year, probably), and everything that uses it would have to use -blockdev.

2) -drive would be limited to a very small set of suboptions (file, 
cache, if, and the ones in qemu_common_drive_opts) and anything that 
specifies the driver would go through -blockdev.
