I can, however I don't think having to resize your browser window to comfortably view an article is a very good UX, especially when it could be rectified by positioning the content in the middle of the screen.

Right, but can you comfortably view anything over there? Why maximize the browser in the first place?

Thats a bit of a chore with a tiling window manager if you generally have the browser on its own workspace - you either need to spawn new windows around the browser window to push it into the geometry you want, or add borders to it.

It's not a great suggestion for, say, iPad users either...

An iPad isn't nearly big enough to have this problem.

This is what I get for iPad emulation: https://i.imgur.com/FriTf6X.png https://i.imgur.com/gLhqvFO.png

It looks just fine.
