I'm using yabai with SIP enabled. The only thing that is missing is sending a window to another workspace. To do that I launch Mission Control and simply drag the window to desired workspace. It turns out I don't do that often so I can live with that.
The workspaces feature in Aerospace is phenomenal and so much better than native macOS workspaces. I highly recommend it. Also the accordion layout of aerospace is better than Yabai’s stacks, and the way that resizing windows works is also better
I tried it, it's nice. There's an issue where high CPU usage makes it unusable though, last time I checked it was still open. Will probably try again in future.
