> It was a mistake to "release" Ember itself as a 1.0 before Ember.Data was ready.

I would only agree with that if ember.js were useless without ember-data or a similar data-persistence layer. I don't think it would be wise to delay the release of Ember 1.0 RC simply because ember-data is still in alpha. Not everyone is going to be using ember-data, and releasing ember without it lets them solve the data persistence on their own.

Unfortunately how separate Ember.Data is depends on which documentation you read. In general most of the official documentation assumes you're using Ember.Data. That makes it feel missing, not separate.

Very true. I don't think the distinction is clear enough that ember-data is a completely different repo, and I think that's definitely a problem.
