While there may be some value in thinking about things this way, imagine the business plan distortion, the day to day incremental diversion of constructive action, and the possible 'talking down' to target users that could occur, should this become a mantra for customer interaction at any touchpoint.

Survey users and read the surveys,

Educate the user and yourselves,

Repeat.

Just a thought...
