After some experiments (that also included timing) with these scenarios I decided that a deep copy made no sense, nor did nilling. In the end both the shallow copy and the metatable variant were - both ok, although the second ons is slower. The most important aspect to keep + both ok, although the second one is slower. The most important aspect to keep in mind is that references to other nodes in properties no longer can be valid for that copy. We could use two tables (one unique and one shared) or metatables but that only complicates matters.
