While I agree that data munging is very important and very difficult, I disagree that it should be part of every course teaching any kind of data manipulation.

I took a course called data mining at university and it largely consisted of munging data.

Biased by that one course, I would expect anything called "data mining" to contain a lot of practice and theory about cleaning data and a machine learning course to focus on what to do with the cleaned data.
