Speaking of having to rewrite your entire application, play framework has changed how it interops with DI and a number of other significant details every single minor release, forcing significant changes to update versions frequently. We were pretty gung ho about it at first, but basically all our engineers have burned out on it and we are going so far as to embrace the relative stability and, dare I say, simplicity of spring-boot. It's possible that for Scala development it is a fairly good option, and some of the pieces like the typesafe config library are pretty nice, but at this point we consider play to be more like a curse word representing incompatible inflexible garbage.
