The GoF catalog's practical sustainability as a composition-centric system depends on two independently characterized support infrastructures: efficiency meta-patterns (deferred duplication, null objects) manage composition's object proliferation costs, while restraint infrastructure (noop defaults, optional participation) manages composition's cognitive adoption costs — together ensuring that the composition paradigm is sustainable in both computational resources and practitioner effort.
Efficiency and restraint independently address the two cost dimensions (computational and cognitive) that threaten composition's practical sustainability
