Doesn't work with ember-cli versions greater than 3.3.*

[nullrocket]

The latest ember-cli version I could get it to work with is 3.3.*

It looks like the function being patched by the addone https://github.com/ember-cli/ember-cli/blob/02b581c4dbea517cd4855ab0426872c058536a9e/lib/broccoli/ember-app.js#L1535 doesn't exist in later versions.

Will there be any more updates here to get it working again, or should we see tree shaking landing upstream in ember-cli instead?
