In fact, a tarp shelter is more like a modular tent: you can add a floor, a bug net, and anything else you want. The main difference is, you only pick what you need instead of having to carry the entire tent were every part is stiched together, plus you can also upgrade separate parts without having to rebuy the entire thing.
Modern tents, especially "ultralight" ones, tend to be more modular, and in fact become "tarp shelter packages" more than tents.
