I would like to see this extension go away, but only by a small margin.  
Just because it complicates the boot/spawn workflow a bit, which really 
isn't a big deal.

As far as I understand it the benefit is that if you have a use case for 
booting large numbers of the same type of instance then this extension 
allows it to happen faster by sending all of the information to the 
scheduler in one message.  I don't know how useful this actually is in 
practice, but I could see it being helpful for someone.
