I agree with this. We could use the PR process for this review.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1519552711

> * At what stage is atatree ""ready"" to moved in here? At what stage should it become encouraged public API?

My opinion is that Datatree should move into Xarray now, ideally in a way that does not disrupt any existing user code, and that Datatree should become a first-class Xarray object (together with DataArray, and Dataset). Since it's a new feature, we don't necessarily have to be super conservative here. I think it is more than good enough / stable enough in its current state.

> * What's a good way to slowly roll the feature out?

Since Datatree sits _above_ DataArray and Dataset, it should not interfere with any of our existing API. As long as test coverage is good, documentation is solid, and the code style matches the rest of Xarray, I think we can just bring it in.

> * How do I decrease the bus factor on datatree's code? Can I get some code reviews during the merging process? 🙏

I think that it is inevitable that you Tom will be the main owner of the Datatree code at the beginning (as @shoyer was of all of Xarray when he first released it). Over time, if people use it, some fraction of users will become maintainers, starting with the existing dev team. 

> * Should I make a new CI environment just for testing datatree stuff?

Why? Are its dependencies different from Xarray?","{""total_count"": 3, ""+1"": 3, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1519552711
