That's a good thing imho, at least if accompanied by something that gives you the more practical perspective on layers 4 and above as well (which is probably where many curricula fail).
Of course it's more interesting to do fun stuff with fancy JSON APIs or create a funky WiFi mesh, it's even likely to be more relevant to most people's future job since not that many people focus on networking. But it's a foundation that can be interesting and help many optimizations down the road, it simply is not academias primary and exclusive focus to prepare students for some job. Just like many people take other stuff from CS programs that you simply don't learn in a 3 month Python course, undertanding of networking protocols is something that _may_ help and give you an advantage for future problem solving. It might even be thought inspiring enough for you to focus on in the first place.
