The importance of having something like LiveView as part of Phoenix, to me at least, is incredibly clear.
There’s one thing being acknowledged, endorsed or linked even, but it’s quite another being part of a system that you know and are already invested in. That seamlessness is priceless, it drives adoption, instills confidence and has untold benefits in all manner of areas whether now or in the future. Autonomy is crucial too, being 100% aligned with the parent project is extremely important for something that (may become) so integral to it. Then there’s having very particular requirements or thoughts on how to approach and tackle things, which you generally want to do with little or no friction so that your vision remains undiluted.
There are just too many benefits to mention (think about all the books that are going to cover it, the screencasts, blogs, etc etc etc) and so I genuinely believe LiveView being a part of Phoenix is going to be better for all of us in the long run… just think, if it delivers on its promise it will not only be amazing for us, but could help take Elixir and Phoenix to the next level. I’m pretty sure that’s what we all want, right?
