Are you personally using PVSCSI, and/or pvusb, and/or do you know any 
large downstreams and/or user bases that depend on them?
There was never any intention of making xl have every single feature of 
xend; only the features that people cared enough about to argue for / 
implement themselves. The list above was generated from a recent 
discussion of why Oracle and Amazon object to removing xend at this 
time.  If these is an important feature to you, the time to say 
something about it was 1 year ago.
That said, pvusb should be really simple to do once we have the HVM 
hot-plug support; I've got a patch series that just needs to be cleaned 
up and submitted.  It's on my short list of things to do, but 
realistically looking like it's not going to happen for 4.4 (unless we 
reconsider the release cycle length).  If you're interested in taking it 
over, I'd be happy to hand it off to you.
