That makes sense. While it's never been a big problem for me to have windows reordered, I could imagine use cases where that would be a pain. For myself, it's pretty straightforward. I don't need titles, because my window manager always shows a thumbnail of the window contents. But while I may have 10 or 15 windows at a given time, I generally only have a few windows that stay up consistently. The others come and go as I need them.

Firefox does have "pinned tabs" which are a part of what you were saying, they preserve the tabs if you close the browser. I use this for the tabs I always have up, like streaming video, e-mail, and Lemmy.
