Sorry to take so long to respond. Your arguments applies to modules that are external, not internal ones. The article specifically talks about internal abstractions, not abstractions that should be all exposed for external consumption (multiple projects). That is definitely up to the requirements. There is no difference between using a single module with many functions than using many functions inside a feature directory. I would argue the last one make the intent clear while not having to think about another searation (the module file).
