That's indeed probably not a very good idea and I can think of quite a few reasons. One that stands out is that in a real application with lots of aggregations an Entity is probably coupled to a very large portion of all the other business objects in your root, hence a deep clone of a business object might yield in cloning the whole prevalence layer. Another reason is that if there was a change to some business object it would not be available in a previously returned clone, but I suppose that even if I can't think of such a situation it's possible that one could be seeking such behavior.

But these are all hypotheticals. The question you've asked is an "X-Y-problem" (search for it on the web!) that have us chase our own tails. That rather than asking about a specific (and to us unknown) problem you ask about the solution you have thought of to that specific (and to us unknown) problem.
