I genuinely feel it will be (a positive). Like you said, it depends on how we go about it 
If you look at the extremes - the ‘Rails’ way on the one hand, and the gazillion different ways in JS land - Elixir & Phoenix are opting for something far more sane, with the three I mentioned (and perhaps one or two other emerging ideas which seem worthy of exploration).
I don’t think we are going to see a lot of frameworks, purely because Chris, José and the Phoenix core team have been astute enough to make Phoenix flexible and suited to many different needs 
It blew my mind when I discovered you can have more than one Phoenix layer in an Elixir app 
Waaaaaaaaat - we’ve got loads 
I think part of the reason for this is how José and Chris solicit feedback and include the community in conversations and the decision making process. Some of the most popular threads on this forum are in the elixir-news and #phoenix-forum:phoenix-news sections (hopefully soon in the #nerves-forum:nerves-news too!).
When I came to Elixir it was for the speed and scalability, but what I’ve stayed for is the ‘better way of doing things’ - a question I often asked in other languages. I was pleasantly surprised to find the closest thing to an answer here in Elixir
