Chakra-ui uses Styled-system and Emotion. All your points are against those 2 projects, not Chakra directly. Chakra turns Tailwind into a Styled-system theme that can be adapted and changed.

>> Those things alone are reason for never using Chakra for anything serious as these are actual reasons your product/saas/whatever is at a higher risk of failing.

Emotion and other CSS-in-JS libraries are used extensively and don't raise a risk of the project failing.

>> And that's just apart from the fact that the components are not allowing easy overriding

You can use Styled-system to create and extend the existing theme. This is actually a knock against using Tailwind CSS directly since you will need to write custom CSS to override the theme. I've even seen projects where Tailwind is used with Emotion to extend the existing theme.

>> At some point the frontend also randomly crashed for me because of the Popover component and it's usage of Popper.js

I use Chakra (and the Menu component that uses Popper) on my landing page and SaaS and have never had any issues. If your code is open, I can help you debug this.
