Status: OUT
Prototype's position at the maximally-coupled extreme of the creational spectrum (triple implementation burden: mandatory Clone, deep copy for independence, separate Initialize) is structurally bounded by the registry meta-mechanism (Prototype Manager providing key-to-instance lookup that decouples clients from Clone complexity) — but only while the deep-copy requirement for structural independence does not defeat the sharing optimizations that make the registry approach practical.
Registry infrastructure bounds Prototype's coupling extreme, but deep-copy requirements can undermine registry-based sharing
