I am evaluating istio to use it for my next project. Everything works nicely and i am really happy about it. But there is one thing i would like to ask for more clarification.
As https://istio.io/about/feature-stages/ authorization is an alpha feature. And the doc mentions that alpha feature means it can be removed and has no deprecation policy. That makes me a bit uncomfortable to use it in production. So i would like to ask how stable is authorization feature, or the reason why it is still an alpha feature (lack of testing, document, api not stable or performance reason)?
