Let's make this cleaner and more explicit by making clobber file operations configurable at the payload level rather than hardcoding this magic string in this action. I expect we could add something like update_clobber_file to MergeInfo that defaults to true (to preserve existing behaviour) and override it in your task configuration.

If you need any additional pointers here just let me know.

Good point. I've updated the patch to update the CLOBBER file based on update_clobber_file in MergeInfo, which defaults to true.
