This will allow you to create data models that check and enforce strict datatypes for your database api. An end user will be able to easily understand what datatypes your models expect to be present. It should make for a better user experience and encourage people to use the database api.

This will be especially helpful if you decide to allow end users to supply their own arbitrary data processing functions, via the database api.
