Description

Talked to @pzuraq and he mentioned that it's theoretically possible to strip out ember-source code that won't be used due to optional-features. This tooling would be great incentive for apps to invest in moving in the direction the core team/communities deems as the way forward.

Not sure where this would happen, but opening here since it seems like a build time concern

Contributor guide

Research direction
Investigate Ember's optional features system and identify which code paths are conditionally compiled. Study existing build plugins or tools that strip dead code. Design a solution to conditionally exclude module code based on feature flags.
