Using Ember without Ember CLI

I'm starting using Ember, but i don't like this ember cli, so i want use it without. Is this wrong? Should i stick with Ember CLI?

I don't agree with this bundle generation stuff, plus i agree 100% with this guys -> http://ift.tt/1ORH2qu

I love to create my own stuff, but i'm feeling that i'm swimming against the tide, i know?

Ember team will force people to use ember cli? Because if they are, i'm going to suffer to change the application later.

There are big projects using ember without the cli?

Thanks.
