I've found the code gen approach to be very positive. Most of the generated code is minimal app-specific modules that in turn `use` Phoenix modules. This gives you a handy place to insert your customization w/o having to resort to dynamic metaprogramming contortions the way you used to have to in Rails. I also like the philosophy of magical experiences, without magical code. Everything is very traceable. And most of the time you don't even need to use the generators - just make your module, register in the right places, and you're done.
