I'm curious what is meant by a "preview feature, or second preview feature, or..." in a released product?? I don't suppose they are going to remove it later. So in what way is it a preview? Are they signalling that it might have breaking changes in the future?

Yes, they reserve the possibilty to completely redo or even remove these preview features. They are not enabled by default, you have to opt in with a compiler flag.
