IMO, the CompSci department would be the one most severely and immediately affected. Is it not better that the CompSci dept head addresses the issues of their department before the dean has to get involved?

I wonder if there’s anyone higher up in the administration even aware this is happening.

There should be at least a minute at the regular deans meeting about this. Which means the head of the other departments know. When I was there CS was both an engineering degree and a liberal arts degree, so that probably means heads of departments like Mechanical Engineering, and Music have heard of it.

For now it can be a "something CS is taking care of, but you need to be aware of it in case they don't".

The announcement also appears on the department's website. https://cse.umn.edu/cs
