The thing is, 30 years ago wide window borders probably were a good idea. When you realise that, you probably will want to look back at previous systems and see how "windows" have evolved over time, what did they gain and what did they lose over time.
One of the earliest windowing systems, Xerox Star, did not offer any built-in chrome or buttons for the windows. If the programmer did not add "close" button, there was no way to close the window. I don't have an emulator at hand, but I think windows were not resizeable either.
Apple mostly copied that into Lisa, but added two important things in 1984's Mac: "close" button and "resize" button. And yes, you cannot resize the window by dragging its boundaries. Only resize button.
Makers of Amiga Workbench (and GEM) added buttons for quick resizing of the windows.
NeXTSTEP from 1988 was seemingly the first one to use "X" icon to close windows. It still had "resize" button to resize the windows arbitrarily.

I hate apps that make the title bar way too small, as well as the buttons on it, it's nearly impossible to properly grab them with touch, I hate it
