[Openstack] questions on the dynamic loading of virt drivers in nova

I'm familiarizing myself with the nova code and trying to reconcile that
while there is dynamic class based loading in ComputeManager using
import_utils in __init__() there is also a defaulting to the
nova.virt.connection.get_connection function.
That's actually got a big if / else statement of string literals of
known virt drivers, and then loads specific virt drivers from there.
Is there a reason for both approaches? Can we refactor to a point where
we don't need need of a common file with driver specific imports and
string literals? Is there a reason not to?
Thanks,
-Sean
