A composition system that could produce shorter strings is possible (calculate every possible combination with the same decomposition, use the shortest) the system used by NFC is a compromise between conciseness of the output and the computational effort needed to generate it.

If there is a problem with this then it goes deeper than just NFC, but to the rules of how combining characters can or cannot be reordered, and the meaning that the resulting strings have. If there is a problem with that then the problem lies with those rules, rather than NFC which uses them.
