The training is not meant to be patronizing, it's meant to insure that your users can use the feature properly. Also, there is to levels of user here--the admin user (who is in control of the feature) and the agent users (the agents who use the product to operate). The forced training is at the agent user level.

From experience, I think mandatory training is necessary otherwise you end up with your agents using fields as they _think_ they should be used instead of how they should be used.
