Ember.Array implements contains but not includes

[alexspeller]

contains is implemented on Ember.Array, but contains was renamed to includes in 2014 - should contains be deprecated in favour of an includes method in ember?

Seem this was discussed on November, 2014 in #5670. It was closed then because this reason. Since the proposal is now Stage 4, I think it is worth revisiting.

@stefanpenner did some work on this #9262

@alexspeller I'm curious if you think this question should be an RFC issue, instead. See CONTRIBUTING.md#requesting-a-feature

if you have an idea that would be nice to have, create an issue on the emberjs/rfcs repo

Moved to RFC emberjs/rfcs#136
