This is good! Thinking is harder than not thinking, so some effort is expected 
It’s important to note, that the generators are learning tools only. Saying you couldn’t use version 1.3 on a project doesn’t make sense because phoenix is not stopping you from writing any kind of code you want.
This could be helpful, but it’s tricky because 1.3 is asking you to actually think about designing your system, and the Phoenix team could try to dream up real’ish apps, but ultimately we can’t design everyone’s application for them. Some larger examples for the community could be helpful, but it’s not something the Phoenix-core team itself should focus on.
