Yabai's wiki has a list of the features you'd lose:

I use it with SIP enabled and haven't had any pain points.

> focus/create/destroy space without animation

I'm amazed by how painful I find this.

I can't disable SIP on my work laptop which means I'm forced to "sit through" the macOS animations as I switch between desktops. Feel like I've wasted hours of my life watching desktops fade-in/-out.

If only this attitude remained:

"Well, let's say you can shave 10 seconds off of the boot time. Multiply that by five million users and thats 50 million seconds, every single day. Over a year, that's probably dozens of lifetimes. So if you make it boot ten seconds faster, you've saved a dozen lives. That's really worth it, don't you think?"

What version of macOS are you running? From the instructions it seems you can re-enable it after with no negative effect on High Sierra, though I assume you’d still lose those features on newer versions.

Neat! Thanks for sharing.

I now run it with SIP enabled on my work machine, not by choice, and I didn't find it made a huge difference. I think the only major thing I lost is easy app movement across spaces, but that is mitigated somewhat by having pre-defined spaces for things I use a lot, such as browser, editor, mail, calendar.
