Nice idea in theory; in practice, it might be tricky to have the organizational incentives aligned to make sure such a course is rigorous enough to be useful, rather than yet another worthless and trivial humanities requirement (at my large public research university with a strong CS program, faculty essentially compete for students based on how little work their gen ed courses are---no joke---and our required CS ethics class was similarly light).
And not just rigorous enough, but also engaging enough that even the "apolitical" students find it interesting. (The students who naturally find an ethics course interesting are the ones who will still find it useful but ultimately need it least.)
