TBH security is someone the source of the issues, as it often involves adding randomness. For example, replacing deterministic hashes by keyed hashes to protect from hash flooding DoS led to deterministic output becoming nondeterministic (e.g. when displaying a hash table in its natural order). Sorting had to be added to that kind of output.
