| Those using the add-on would need to mechanically adjust any uses of `myArray.copy(deep)` to `copy(myArray, deep)` in order to avoid the deprecation message. | ||

| I cannot see a way to notify the user through deprecation at runtime about their own objects that are extending `Copyable` and contain `copy()` methods that will no longer be called when the deprecated `Ember.copy()` method goes away. Our best bet for this might be to supply a new eslint warning that flags the import of `Copyable`. |

"at extend time" - Since extend is defined in system.core-object, also in ember-runtime, implementing a deprecation at that level might be architecturally sound. The check would be a small tax on every extend, though, which seems severe. @rwjblue Was that where you intended to put it? Or somewhere else in the chain of activity "at extend time"?
