Nearly every techie and non-techie I know has a bazillion tabs open 100% of the time. The likelihood that even the top 10 are all single-column text is 0%. And I'd sooner read web pages hot off a dot matrix printer than constantly pecking at the edge of an un-maximized window, resizing it like some kind of meth-addled chicken.
Note: I may be overstating slightly for effect.
Oh the irony that lots complain that mainstream OSes window managers are oh so poor when all people seem to be able to do is fullscreen everything and then tab around.
Meanwhile, macOS gave up on the absolutely brilliant if misunderstood Mac OS X green + a.k.a "zoom" which would miraculously resize windows to the maximum size of its content but no more.
Did people lose the old art, or have you never managed to grasp the "new" one?
Maybe someone should invent a tiling tab manager for the web browser.

It’s still there. Window > Zoom from the menu bar, or ⌥ + click the green window button.
E.g., there's no way for you to easily send me the desktop state of the open window sizes and dimensions you have in mind. And even then, I'd have to hack the window decorations and fonts myself. I'm back to meth-addled chicken pecking!
