That's true (well, unless you keep a log of which chunks have been moved so
that you can continue or revert the operation after such incident.) 

Perhaps the feature could still be offered as a "dangerous" operation
requiring confirmation, --force switch or such? In my case, I have a
backup.

I would assume not all the other parted options are 100% power-loss proof -
for example the various fs resize operations?
