I would say more developers like this about the JavaScript ecosystem than don't. It's awesome to be able to use new features and kick their tires before the core engine dev teams invest resources in building them out. It seems like a win / win situation here. js devs get to use and reason about tomorrow's features today and help guide whether or not they are a good idea or even more easily come up with new ones. Js engine devs get to see how features are used and whether or not to invest. Honestly what is not to like about this?
