@swpalmer @hjohn @andy-goryachev-oracle @kevinrushforth 
I think that the [Preferences API](https://gist.github.com/mstr2/9f46f92c98d3c86aa6a0b4224a9a6548) has evolved quite well. There were quite some discussions on the mailing list, as well as here on GitHub. Given that there haven't been new arguments in favor or against this feature in a while, I'd like to wrap up the discussion on whether we want this in JavaFX.

The main reason why I think this should go into core JavaFX is that it is adding a useful feature that can only be reasonably provided by the native windowing toolkits, and not by third-party libraries.
