I could definitely see eye-rolls if students who know (of) git are being taught about CVS. But I'm not sure it matters that much. This stuff is tangential to the core course material, so a student (or small project group) can pick the tool of their choice. If they know something newer or better than suggested, great.
The way DevOps evolved was sort of a mess anyway but welcome to tech.
I sort of agree more broadly but I can also see a lot of students rolling their eyes at using outdated tools which is probably less the case in other disciplines.
