agreed. it has been over 15 years since I graduated from a pretty good CS program in an engineering school, and we definitely had math professors teaching many core courses that were math focused (e.g. http://www.cs.cornell.edu/courses/cs2800/2015sp/ http://www.cs.cornell.edu/courses/cs2800/2015sp/). and professors from other engineering disciplines taught courses across (e.g. OR/IE profs doing stats). this might have been possible at my school and not possible elsewhere based on how the different departments are focused / rewarded / isolated. more math profs might have been interested in getting CS experience back then.
