People often try to implement things with a hypothetical future use in mind. It may even be a realistic future, but it is never the less a future that does not need to be dealt with right now. Adding code for things that aren't actually in play means adding something you can't actually test. It means people may abuse what you set up later (and introduce bugs) if the actual future turns out different than you planned. Taken to the extreme, this planning for the future turns one into an architecture astronaut.
