Yes.

It's unavoidable unless we're going to try and review and merge a huge 
number of patches at once.  If we do that, nothing's going to get 
reviewed properly and I want to avoid another qdev-style merge and then 
ask for forgiveness afterwards :-)

I'm not hugely opposed to just not merging the -qmp2 flag but I don't 
really see it as a bad thing.  -qmp2 disappears once round two is merged 
and round 2 should be very easy to merge once round 1 is merged.

The command conversion is extremely straight forward minus some of the 
qdev error propagation changes.
