I have a request to do $SUBJECT in relation to a V2V workflow. The use
case here is conversion of a VM/Physical which was previously powered
off. We want to move its data, but we don't want to be powering on
stuff which wasn't previously on.

This would involve an api change, and a hopefully very small change in
drivers to support it. Technically I don't see it as an issue.

However, is it a change we'd be willing to accept? Is there any good
reason not to do this? Are there any less esoteric workflows which
might use this feature?

I don't know if it qualifies as less esoteric, but I would use this for OVB[1]. When we create the "baremetal" VMs there's no need to actually power them on since the first thing we do with them is shut them down again. Their initial footprint is pretty small so it's not a huge deal, but it is another potential use case for this feature.
