absolutely. when we had an electrician dig new chases to completely rewire the electricity in my grandparents apartment in a century old building, i asked him to add an additional pipe everywhere so that i could wire ethernet as well. every room got at least one or two, some more. the key thing was that even though we didn't use most of those extra pipes, adding them barely cost more than the material, because the work to dig the chases didn't change.
