While I usually detest giant footers, this is one use-case they lend benefit to, without causing a large empty space (which some people would then want to fill with an image). I agree from a UX perspective that I prefer when sites act the way I expect them to, and not try to do novel calculations of stuff (minus usability stuff like the ‘dead zone’ dropdown menu polygon calculation). On most pages, I expect a reading section to start when I scroll past a heading, and I prefer anchors to deliver the heading at the top of my viewport.
