This should probably be per-community configurable. Since even on Code Golf, not all tags are meaningful on answers, one might say that only tags derived from question tags are allowed, but a site can define “category implied tags” that cannot actually be used, but are treated as if they were used on all questions of the category they were defined for. For example, on the Code Golf category Challenges, there would be an implied “language” tag which has all languages as subcategories, enabling all answers to a challenge to use language tags, but not tags like code-golf or alternative-scoring which don't make sense for answers.
