Moving lib folder into app

Hi, I’m considering moving my lib folder into the app folder in order to get ember-cli-code-coverage to work properly for me. A coworker suggested that would cause issues with ember-engine but I don’t seem to have that problem

I’m not sure about this in the context of engines, but I believe everything inside app is pushed into the final dist output. Which means you may end up shipping things you don’t need to the client.
