When a decorable object is instantiated, the associated DecorationContainer allocates the necessary space for all the decorations at once. However, the codebase currently contains a large number of decorations whose type is a std::unique_ptr. This defeats the purpose of allocating all decorations together and introduces a performance penalty.

We need to go over all of these decorations and evaluate the feasibility of changing their type from std::unique_ptr to boost::optional.
