This is technically a breaking change to the API, but I'm fairly certain hardly anyone is using these methods (the pagination functionality in the API is pretty useless) Can always add them back if it becomes an issue

The feature has stuck around since the early days - and solves a problem which really should never occur.
It was pretty useless (and wasn't implemented on SQL/Mongo storage types.) Data is naturally cleaned up over time as users are loaded/saved.
