It’s relatively alright for something that’s called unstable. There is also testing which is tested for at least 10 days. And you can mix and match, but that’s not recommended either.
I wouldn’t put it on my server. And I wouldn’t recommend it to someone who isn’t okay with fixing the occasional hiccup. But I’ve been using it for years and I like it.
However, mind that it’s not supported and they do not pay attention to security fixes.
