The motivation behind this change is the idea that constructing a new instance of an object is the job of the constructor. One big benefit of this structure (with the addition of helpers for convenience) is that calls for emplacing instances (like `std::make_shared`, or `std::vector::emplace_back`) work without any difficulty. This would not be true for static construction functions.
