Presumably it's because you're taking a trip over iscsi instead of using
the native attachment mechanism for the technology that you're using? If
so, that's a valid argument, but it's hard to see the tradeoff working
in favor of adding all these drivers to nova as well.

If cinder doesn't support backend-specific connectors, maybe that's
something we could work on? People keep saying that "cinder is where I
put my storage, that's how I want to back my instances" when it comes to
justifying BFV, and that argument is starting to resonate with me more
and more.
