The main feature that requires SIP to be disabled is managing multiple workspaces without animating the swap between them which saves a ton of time and is key to the seamless feel. There are some workarounds of course, but there's no way to get around the 1-2s animation without turning off SIP.

Under accessibility toggling reduce motion serves a similar purpose. It is not instantaneous like yabai but I’ve found it quick enough to not be frustrating as someone who utilizes spaces heavily.
