Another alternative is yobai (+ skhd) https://github.com/koekeishiya/yabai

I switched to it after having some issues with rectangle sending some of my windows into the abyss (way outside of the screen) which forced me to kill the app and restart it to get it back. But if Rectangle works for you that's good too, it's probably easier to configure.

yabai is the only alternative if you are used to i3wm or bspwm

Did you disable kernel security to inject the window server extensions? I don’t understand the repercussions so I’m a little reluctant to.

Same, and this really makes it a deal breaker for me in my company's MacBook pro.

You don't have to do that, it works without. Those are for addons I believe.
