With a button you just press it to close the windows for a short stint of faster driving where having the windows down is uncomfortable. With a flange you’d probably be more inclined to leave them open because of the effort required to close them while driving. I think having your windows open even for a few short drives leads to more energy usage by increased drag than the window servo uses in the whole cars’ lifetime. So I don’t think it is any more environmentally friendly.
