I understand the desire to do this, but this is none the less a
semantic change to the behaviour of the APIs. It is the same
situation as arbitrarily changing the defaults for any part of
the domain XML.
I'm aware of that, but at certain point it IMO doesn't make sense to try
to stick with a prehistoric format just for the sake of it and IMO this
is it.
Nonetheless, it's not strictly required. I can just use the new format
for the non-shared-storage migration rather than globally if we want to
stay in the cave.
