On the other hand, pages that stay in a narrow column in the middle when I widen the window really infuriate me, because I explicitly asked for wider columns and am not getting it.

The whole idea is that when you have the window at a comfortable width, the content in all your other tabs should also be.
The web is such a shit place in terms of design. This is probably why I like reading books and magazines in print. At least the lay out is done by a professional who doesn't have a title "UX/UI" designer and doesn't have a Behance/Dribble portfolio. These people are professionals and they conduct themselves as such.
Different people have different workflows. Many people I know only have 1 browser window open, always maximized, with a ton of tabs open in it. They definitely won't go about resizing the window for no good reason. I don't think any mainstream website relies on the user resizing the browser window for, what I think are, good reasons.
macOS, on the other hand, explicitly advertised having an "immersive" fullscreen mode (with a dedicated button in the past).
