When duplicating an Elasticube with data security rules, the security rules are not duplicated.
If I want to create a new version of an Elasticube, distinct from the original, normally I will want to keep the rules, but this does not happen.
Being given a choice would be ideal, but if there had to be default behaviour, it makes more sense to just keep the rules, as they can easily be deleted if they are not needed, but re-creating them, even via REST API can be fiddly.
