If you are planning to re-image an image on a bootable volume then yes you should use a force parameter. I have lost the discussion about this on PTG. What is the main use cases? This seems to me something that could be leveraged with the current revert-to-snapshot API, which would be even better. The flow would be:
1 - create a volume from image 2 - create an snapshot 3 - do whatever you wan't 4 - revert the snapshot Would that help in your the use cases?
