I actually really hate that behavior. I arrange windows to provide the information I need. That's usually a strip on the left to show the mailbox pane of my mail window, a strip below that for slack channels, and a finder window on a scratch directory. To the right are my work windows. Window snapping makes that impossible, about the only thing you can do is pretend you're using a tiling WM and cmd-tab any time you need to see anything, or waste an inflexible chunk of screen on it.
