Yes, you could. It will all depend on what you’re aiming for. Perhaps you want the most little geometry as possible and you are saving poly’s wherever you can. Or maybe you can afford more geometry for a better detailed model and so you can go and add more polygons so your model can be more high definition. Sometimes it can be a workflow limitation, other times you can go crazy and add much more. So it’ll all depends. Also it will depend if it’s for games and then it’ll depend on the engine. So like always in Blender, it depends. But don’t be afraid to do it your way, mostly there’s no right or wrong, just the approach you decide to take.
