no, not for all getters/setters - that would be a bad idea IMO. I'd 
probably only do it for getters/setters passing objectStorages if the 
model relies on the usage of special add/remove methods - but that's 
just my personal estimation - no recommendation. Until now I actually 
never passed cloned objects directly by setters/getters but after 
thinking about it might do so in future (for objectStorages and/or where 
appropriate).
