Disagree, as one who uses the tiling system having different windows in a 2x2 grid or half + 2x1 grid. While vertical real estate is more valuable than horizontal for reading, vertical browser tabs would cramp the horizontal space too much, and having the browser in the top half just dont work well exactly because of the value of vertical space.

Just sandbox it instead.

For one thing if you’re snapshotting your subvolumes for backup purposes then it will ignore nested subvolumes. Eg you dont want to preserve snapshots of huge installed game directories, cache directories, logs or docker / podman images, usually. Saves a lot of space.

Also you can tune copy on write on a subvolume, which is great for some use cases for performance.
